Check Digit Verification of cas no
The CAS Registry Mumber 83603-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83603-32:
(7*8)+(6*3)+(5*6)+(4*0)+(3*3)+(2*3)+(1*2)=121
121 % 10 = 1
So 83603-32-1 is a valid CAS Registry Number.
