197178-43-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197178-43-1 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 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197178-43:
(8*1)+(7*9)+(6*7)+(5*1)+(4*7)+(3*8)+(2*4)+(1*3)=181
181 % 10 = 1
So 197178-43-1 is a valid CAS Registry Number.
