Check Digit Verification of cas no

The CAS Registry Mumber 1216962-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,6,9,6 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1216962-67:
(9*1)+(8*2)+(7*1)+(6*6)+(5*9)+(4*6)+(3*2)+(2*6)+(1*7)=162
162 % 10 = 2
So 1216962-67-2 is a valid CAS Registry Number.
