Check Digit Verification of cas no

The CAS Registry Mumber 196597-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,5,9 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 196597-79:
(8*1)+(7*9)+(6*6)+(5*5)+(4*9)+(3*7)+(2*7)+(1*9)=212
212 % 10 = 2
So 196597-79-2 is a valid CAS Registry Number.
