73497-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73497-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,9 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73497-76:
(7*7)+(6*3)+(5*4)+(4*9)+(3*7)+(2*7)+(1*6)=164
164 % 10 = 4
So 73497-76-4 is a valid CAS Registry Number.
