Check Digit Verification of cas no
The CAS Registry Mumber 61951-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,5 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61951-81:
(7*6)+(6*1)+(5*9)+(4*5)+(3*1)+(2*8)+(1*1)=133
133 % 10 = 3
So 61951-81-3 is a valid CAS Registry Number.
