Check Digit Verification of cas no
The CAS Registry Mumber 474510-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,5,1 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 474510-57:
(8*4)+(7*7)+(6*4)+(5*5)+(4*1)+(3*0)+(2*5)+(1*7)=151
151 % 10 = 1
So 474510-57-1 is a valid CAS Registry Number.
