Check Digit Verification of cas no

The CAS Registry Mumber 733769-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,3,7,6 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 733769-91:
(8*7)+(7*3)+(6*3)+(5*7)+(4*6)+(3*9)+(2*9)+(1*1)=200
200 % 10 = 0
So 733769-91-0 is a valid CAS Registry Number.
