64812-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64812-67-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,8,1 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64812-67:
(7*6)+(6*4)+(5*8)+(4*1)+(3*2)+(2*6)+(1*7)=135
135 % 10 = 5
So 64812-67-5 is a valid CAS Registry Number.
