Check Digit Verification of cas no

The CAS Registry Mumber 1213236-23-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,2,3 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1213236-23:
(9*1)+(8*2)+(7*1)+(6*3)+(5*2)+(4*3)+(3*6)+(2*2)+(1*3)=97
97 % 10 = 7
So 1213236-23-7 is a valid CAS Registry Number.
