143422-73-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143422-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,2 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143422-73:
(8*1)+(7*4)+(6*3)+(5*4)+(4*2)+(3*2)+(2*7)+(1*3)=105
105 % 10 = 5
So 143422-73-5 is a valid CAS Registry Number.
