197172-29-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197172-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,7 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197172-29:
(8*1)+(7*9)+(6*7)+(5*1)+(4*7)+(3*2)+(2*2)+(1*9)=165
165 % 10 = 5
So 197172-29-5 is a valid CAS Registry Number.
