Check Digit Verification of cas no

The CAS Registry Mumber 162299-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,2,9 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 162299-79:
(8*1)+(7*6)+(6*2)+(5*2)+(4*9)+(3*9)+(2*7)+(1*9)=158
158 % 10 = 8
So 162299-79-8 is a valid CAS Registry Number.
