73466-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73466-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,6 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73466-68:
(7*7)+(6*3)+(5*4)+(4*6)+(3*6)+(2*6)+(1*8)=149
149 % 10 = 9
So 73466-68-9 is a valid CAS Registry Number.
