Check Digit Verification of cas no
The CAS Registry Mumber 229-72-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,2 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 229-72:
(5*2)+(4*2)+(3*9)+(2*7)+(1*2)=61
61 % 10 = 1
So 229-72-1 is a valid CAS Registry Number.
