Check Digit Verification of cas no

The CAS Registry Mumber 78346-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,4 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78346-07:
(7*7)+(6*8)+(5*3)+(4*4)+(3*6)+(2*0)+(1*7)=153
153 % 10 = 3
So 78346-07-3 is a valid CAS Registry Number.

Carbostyril derivatives

-

, (2008/06/13)

Novel carbostyril derivative and its salt represented by the general formula (1), STR1 wherein R1 is a hydrogen atom, a lower alkyl group, a lower alkenyl group or a phenyl-lower alkyl group; R2 is a hydrogen atom, a lower alkyl group or a group of the formula STR2 wherein A is a lower alkylene group; R3 is a lower alkyl group, a hydroxy lower alkyl group, a lower alkoxy-lower alkyl group, a lower alkanoyloxy-lower alkyl group or a benzoyloxy-lower alkyl group; and R4 is a C3-10 -cycloalkyl group which may have at least one hydroxyl group as the substituent(s) in the cycloalkyl ring, a C3-10 -cycloalkyl-lower alkyl group, a phenyl group, a phenyl-lower alkyl group which may have at least one lower alkoxy group as the substituent(s) in the phenyl ring, a lower alkyl group which may have at least one hydroxyl group as the substituent(s), a heterocyclic ring residue or a lower alkyl group having one heterocyclic ring residue as the substituent; further, R3, R4 and the adjacent nitrogen atom, as well as with or without another nitrogen atom, may form a group of the formula STR3 (wherein R5 is a phenyl group, a C3-10 -cycloalkyl group or a phenyl-lower alkyl group; and B is a methine group or a nitrogen atom); the carbon-carbon bond between the 3- and 4-positions in the carbostyril skeleton is a single or double bond; the substituted position of the group of the formula STR4 is any one of 5-, 6-, 7- or 8-position in the carbostyril skeleton; when the group of the formula STR5 is substituted at 5-, 6-, 7- or 8-position in the carbostyril skeleton, then R2 is a hydrogen atom or a lower alkyl group; alternatively, when R2 is a group of the formula STR6 then 5-, 6-, 7- and 8-positions in the carbostyril skeleton are hydrogen atoms and are not substituted with groups of the formula STR7 and when R3 is a lower alkyl group, then R4 should be neither of a C3-10 -cycloalkyl group, a C3-10 -cycloalkyl-lower alkyl group nor a lower alkyl group, having effects for preventing and treating thrombosis and embolism.
