64657-40-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64657-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64657-40:
(7*6)+(6*4)+(5*6)+(4*5)+(3*7)+(2*4)+(1*0)=145
145 % 10 = 5
So 64657-40-5 is a valid CAS Registry Number.
