Check Digit Verification of cas no

The CAS Registry Mumber 83763-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,6 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83763-84:
(7*8)+(6*3)+(5*7)+(4*6)+(3*3)+(2*8)+(1*4)=162
162 % 10 = 2
So 83763-84-2 is a valid CAS Registry Number.
