Check Digit Verification of cas no
The CAS Registry Mumber 133791-17-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133791-17:
(8*1)+(7*3)+(6*3)+(5*7)+(4*9)+(3*1)+(2*1)+(1*7)=130
130 % 10 = 0
So 133791-17-0 is a valid CAS Registry Number.
