Check Digit Verification of cas no
The CAS Registry Mumber 722553-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,2,5,5 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 722553-24:
(8*7)+(7*2)+(6*2)+(5*5)+(4*5)+(3*3)+(2*2)+(1*4)=144
144 % 10 = 4
So 722553-24-4 is a valid CAS Registry Number.
