Check Digit Verification of cas no
The CAS Registry Mumber 5858-33-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5858-33:
(6*5)+(5*8)+(4*5)+(3*8)+(2*3)+(1*3)=123
123 % 10 = 3
So 5858-33-3 is a valid CAS Registry Number.
