Check Digit Verification of cas no

The CAS Registry Mumber 857732-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,7,3 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 857732-41:
(8*8)+(7*5)+(6*7)+(5*7)+(4*3)+(3*2)+(2*4)+(1*1)=203
203 % 10 = 3
So 857732-41-3 is a valid CAS Registry Number.
