Check Digit Verification of cas no
The CAS Registry Mumber 4512-46-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4512-46:
(6*4)+(5*5)+(4*1)+(3*2)+(2*4)+(1*6)=73
73 % 10 = 3
So 4512-46-3 is a valid CAS Registry Number.
