Check Digit Verification of cas no
The CAS Registry Mumber 21514-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,1 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21514-32:
(7*2)+(6*1)+(5*5)+(4*1)+(3*4)+(2*3)+(1*2)=69
69 % 10 = 9
So 21514-32-9 is a valid CAS Registry Number.
