Check Digit Verification of cas no
The CAS Registry Mumber 5096-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,9 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5096-83:
(6*5)+(5*0)+(4*9)+(3*6)+(2*8)+(1*3)=103
103 % 10 = 3
So 5096-83-3 is a valid CAS Registry Number.
