64634-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64634-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,3 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 64634-03:
(7*6)+(6*4)+(5*6)+(4*3)+(3*4)+(2*0)+(1*3)=123
123 % 10 = 3
So 64634-03-3 is a valid CAS Registry Number.
