73664-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73664-54-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,6 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73664-54:
(7*7)+(6*3)+(5*6)+(4*6)+(3*4)+(2*5)+(1*4)=147
147 % 10 = 7
So 73664-54-7 is a valid CAS Registry Number.
