73143-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73143-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,4 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73143-22:
(7*7)+(6*3)+(5*1)+(4*4)+(3*3)+(2*2)+(1*2)=103
103 % 10 = 3
So 73143-22-3 is a valid CAS Registry Number.
