Check Digit Verification of cas no

The CAS Registry Mumber 1268686-65-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,6,8 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1268686-65:
(9*1)+(8*2)+(7*6)+(6*8)+(5*6)+(4*8)+(3*6)+(2*6)+(1*5)=212
212 % 10 = 2
So 1268686-65-2 is a valid CAS Registry Number.
