Check Digit Verification of cas no
The CAS Registry Mumber 474543-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,5,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 474543-08:
(8*4)+(7*7)+(6*4)+(5*5)+(4*4)+(3*3)+(2*0)+(1*8)=163
163 % 10 = 3
So 474543-08-3 is a valid CAS Registry Number.
