Check Digit Verification of cas no
The CAS Registry Mumber 474918-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,9,1 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 474918-33:
(8*4)+(7*7)+(6*4)+(5*9)+(4*1)+(3*8)+(2*3)+(1*3)=187
187 % 10 = 7
So 474918-33-7 is a valid CAS Registry Number.
