64490-14-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64490-14-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,9 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 64490-14:
(7*6)+(6*4)+(5*4)+(4*9)+(3*0)+(2*1)+(1*4)=128
128 % 10 = 8
So 64490-14-8 is a valid CAS Registry Number.
