Check Digit Verification of cas no
The CAS Registry Mumber 21297-24-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,9 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21297-24:
(7*2)+(6*1)+(5*2)+(4*9)+(3*7)+(2*2)+(1*4)=95
95 % 10 = 5
So 21297-24-5 is a valid CAS Registry Number.
