76640-46-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76640-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,4 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76640-46:
(7*7)+(6*6)+(5*6)+(4*4)+(3*0)+(2*4)+(1*6)=145
145 % 10 = 5
So 76640-46-5 is a valid CAS Registry Number.
