Check Digit Verification of cas no

The CAS Registry Mumber 1258237-35-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,3 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1258237-35:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*3)+(3*7)+(2*3)+(1*5)=162
162 % 10 = 2
So 1258237-35-2 is a valid CAS Registry Number.
