197177-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197177-72-3 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 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 197177-72:
(8*1)+(7*9)+(6*7)+(5*1)+(4*7)+(3*7)+(2*7)+(1*2)=183
183 % 10 = 3
So 197177-72-3 is a valid CAS Registry Number.
