173143-79-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173143-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,1,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173143-79:
(8*1)+(7*7)+(6*3)+(5*1)+(4*4)+(3*3)+(2*7)+(1*9)=128
128 % 10 = 8
So 173143-79-8 is a valid CAS Registry Number.
