64675-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64675-08-7 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 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64675-08:
(7*6)+(6*4)+(5*6)+(4*7)+(3*5)+(2*0)+(1*8)=147
147 % 10 = 7
So 64675-08-7 is a valid CAS Registry Number.
