Check Digit Verification of cas no
The CAS Registry Mumber 51698-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,9 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51698-33:
(7*5)+(6*1)+(5*6)+(4*9)+(3*8)+(2*3)+(1*3)=140
140 % 10 = 0
So 51698-33-0 is a valid CAS Registry Number.
