4660-19-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4660-19-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4660-19:
(6*4)+(5*6)+(4*6)+(3*0)+(2*1)+(1*9)=89
89 % 10 = 9
So 4660-19-9 is a valid CAS Registry Number.
