Check Digit Verification of cas no

The CAS Registry Mumber 137789-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,8 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137789-81:
(8*1)+(7*3)+(6*7)+(5*7)+(4*8)+(3*9)+(2*8)+(1*1)=182
182 % 10 = 2
So 137789-81-2 is a valid CAS Registry Number.
