Check Digit Verification of cas no
The CAS Registry Mumber 266330-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,6,3,3 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 266330-02:
(8*2)+(7*6)+(6*6)+(5*3)+(4*3)+(3*0)+(2*0)+(1*2)=123
123 % 10 = 3
So 266330-02-3 is a valid CAS Registry Number.
