Check Digit Verification of cas no

The CAS Registry Mumber 82937-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,3 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82937-31:
(7*8)+(6*2)+(5*9)+(4*3)+(3*7)+(2*3)+(1*1)=153
153 % 10 = 3
So 82937-31-3 is a valid CAS Registry Number.
