Check Digit Verification of cas no
The CAS Registry Mumber 4833-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4833-91:
(6*4)+(5*8)+(4*3)+(3*3)+(2*9)+(1*1)=104
104 % 10 = 4
So 4833-91-4 is a valid CAS Registry Number.
