Check Digit Verification of cas no

The CAS Registry Mumber 137197-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,9 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137197-17:
(8*1)+(7*3)+(6*7)+(5*1)+(4*9)+(3*7)+(2*1)+(1*7)=142
142 % 10 = 2
So 137197-17-2 is a valid CAS Registry Number.
