2001-16-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2001-16-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,0 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2001-16:
(6*2)+(5*0)+(4*0)+(3*1)+(2*1)+(1*6)=23
23 % 10 = 3
So 2001-16-3 is a valid CAS Registry Number.
