Check Digit Verification of cas no
The CAS Registry Mumber 4493-66-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,9 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4493-66:
(6*4)+(5*4)+(4*9)+(3*3)+(2*6)+(1*6)=107
107 % 10 = 7
So 4493-66-7 is a valid CAS Registry Number.
