Check Digit Verification of cas no
The CAS Registry Mumber 5330-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5330-72:
(6*5)+(5*3)+(4*3)+(3*0)+(2*7)+(1*2)=73
73 % 10 = 3
So 5330-72-3 is a valid CAS Registry Number.
