64671-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64671-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 64671-55:
(7*6)+(6*4)+(5*6)+(4*7)+(3*1)+(2*5)+(1*5)=142
142 % 10 = 2
So 64671-55-2 is a valid CAS Registry Number.
