Check Digit Verification of cas no
The CAS Registry Mumber 519148-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,1,4 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 519148-63:
(8*5)+(7*1)+(6*9)+(5*1)+(4*4)+(3*8)+(2*6)+(1*3)=161
161 % 10 = 1
So 519148-63-1 is a valid CAS Registry Number.

Heterocyclic analogs of pleiadene. 73. Intramolecular cyclization of cinnamoyl- and o-chlorobenzoylperimidines
Borovlev,Demidov,Pozharskii
, p. 1091 - 1095 (2002)
We have carried out the intramolecular cyclization of the anions of 4(9)- and 6(7)-cinnamoylperimidines and also of 4(9)-o-chorobenzoylperimidine. These partially hydrogenated pyrido- and quino[1,2,3-cd]perimidines were obtained for the first time. Their
