Check Digit Verification of cas no
The CAS Registry Mumber 117-69-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 117-69:
(5*1)+(4*1)+(3*7)+(2*6)+(1*9)=51
51 % 10 = 1
So 117-69-1 is a valid CAS Registry Number.
