Check Digit Verification of cas no
The CAS Registry Mumber 29263-94-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,2,6 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 29263-94:
(7*2)+(6*9)+(5*2)+(4*6)+(3*3)+(2*9)+(1*4)=133
133 % 10 = 3
So 29263-94-3 is a valid CAS Registry Number.
