76640-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76640-37-4 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 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76640-37:
(7*7)+(6*6)+(5*6)+(4*4)+(3*0)+(2*3)+(1*7)=144
144 % 10 = 4
So 76640-37-4 is a valid CAS Registry Number.
