64743-14-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64743-14-2 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, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 64743-14:
(7*6)+(6*4)+(5*7)+(4*4)+(3*3)+(2*1)+(1*4)=132
132 % 10 = 2
So 64743-14-2 is a valid CAS Registry Number.
