Check Digit Verification of cas no

The CAS Registry Mumber 77239-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,3 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77239-94:
(7*7)+(6*7)+(5*2)+(4*3)+(3*9)+(2*9)+(1*4)=162
162 % 10 = 2
So 77239-94-2 is a valid CAS Registry Number.
