Check Digit Verification of cas no
The CAS Registry Mumber 197-69-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197-69:
(5*1)+(4*9)+(3*7)+(2*6)+(1*9)=83
83 % 10 = 3
So 197-69-3 is a valid CAS Registry Number.
