664341-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 664341-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,3,4 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 664341-72:
(8*6)+(7*6)+(6*4)+(5*3)+(4*4)+(3*1)+(2*7)+(1*2)=164
164 % 10 = 4
So 664341-72-4 is a valid CAS Registry Number.
