64743-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64743-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,4 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 64743-45:
(7*6)+(6*4)+(5*7)+(4*4)+(3*3)+(2*4)+(1*5)=139
139 % 10 = 9
So 64743-45-9 is a valid CAS Registry Number.
