Check Digit Verification of cas no

The CAS Registry Mumber 251113-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,1,1 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 251113-73:
(8*2)+(7*5)+(6*1)+(5*1)+(4*1)+(3*3)+(2*7)+(1*3)=92
92 % 10 = 2
So 251113-73-2 is a valid CAS Registry Number.

A new procedure for the asymmetric synthesis of imidazolidines and vicinal diamines is reported. The 1,3-dipolar cycloaddition between nonracemic p-tolylsulfinimines and azomethine ylides generated in situ from aiminoesters and LDA produces N-sulfinylimid
