Check Digit Verification of cas no

The CAS Registry Mumber 371943-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,1,9,4 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 371943-54:
(8*3)+(7*7)+(6*1)+(5*9)+(4*4)+(3*3)+(2*5)+(1*4)=163
163 % 10 = 3
So 371943-54-3 is a valid CAS Registry Number.
