Check Digit Verification of cas no
The CAS Registry Mumber 497933-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,9,3 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 497933-14:
(8*4)+(7*9)+(6*7)+(5*9)+(4*3)+(3*3)+(2*1)+(1*4)=209
209 % 10 = 9
So 497933-14-9 is a valid CAS Registry Number.
