76643-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76643-96-4 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 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76643-96:
(7*7)+(6*6)+(5*6)+(4*4)+(3*3)+(2*9)+(1*6)=164
164 % 10 = 4
So 76643-96-4 is a valid CAS Registry Number.
