Check Digit Verification of cas no

The CAS Registry Mumber 139765-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,6 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139765-71:
(8*1)+(7*3)+(6*9)+(5*7)+(4*6)+(3*5)+(2*7)+(1*1)=172
172 % 10 = 2
So 139765-71-2 is a valid CAS Registry Number.
