Check Digit Verification of cas no

The CAS Registry Mumber 92741-33-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,7,4 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92741-33:
(7*9)+(6*2)+(5*7)+(4*4)+(3*1)+(2*3)+(1*3)=138
138 % 10 = 8
So 92741-33-8 is a valid CAS Registry Number.
