Check Digit Verification of cas no

The CAS Registry Mumber 194922-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,9,2 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 194922-77:
(8*1)+(7*9)+(6*4)+(5*9)+(4*2)+(3*2)+(2*7)+(1*7)=175
175 % 10 = 5
So 194922-77-5 is a valid CAS Registry Number.

Mizuno, Masashi,Kanai, Motomu,Iida, Akira,Tomioka, Kiyoshi

, p. 10699 - 10708 (1997)

Enantioselective nucleophilic opening reactions of cyclohexene oxide and 3-phenyloxetane were achieved by the combination of an external chiral ligand and organolithiums in the presence of boran trifluoride to give the corresponding alcohols in up to 47% ee.
