197141-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197141-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,4 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 197141-57:
(8*1)+(7*9)+(6*7)+(5*1)+(4*4)+(3*1)+(2*5)+(1*7)=154
154 % 10 = 4
So 197141-57-4 is a valid CAS Registry Number.
