Check Digit Verification of cas no

The CAS Registry Mumber 796848-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,6,8,4 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 796848-79:
(8*7)+(7*9)+(6*6)+(5*8)+(4*4)+(3*8)+(2*7)+(1*9)=258
258 % 10 = 8
So 796848-79-8 is a valid CAS Registry Number.
