Check Digit Verification of cas no
The CAS Registry Mumber 2172-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2172-33:
(6*2)+(5*1)+(4*7)+(3*2)+(2*3)+(1*3)=60
60 % 10 = 0
So 2172-33-0 is a valid CAS Registry Number.
