Check Digit Verification of cas no

The CAS Registry Mumber 637757-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,7,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 637757-16:
(8*6)+(7*3)+(6*7)+(5*7)+(4*5)+(3*7)+(2*1)+(1*6)=195
195 % 10 = 5
So 637757-16-5 is a valid CAS Registry Number.
