Check Digit Verification of cas no
The CAS Registry Mumber 21233-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,3 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21233-19:
(7*2)+(6*1)+(5*2)+(4*3)+(3*3)+(2*1)+(1*9)=62
62 % 10 = 2
So 21233-19-2 is a valid CAS Registry Number.
