Check Digit Verification of cas no
The CAS Registry Mumber 33954-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,5 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33954-15:
(7*3)+(6*3)+(5*9)+(4*5)+(3*4)+(2*1)+(1*5)=123
123 % 10 = 3
So 33954-15-3 is a valid CAS Registry Number.
