197146-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197146-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 197146-87:
(8*1)+(7*9)+(6*7)+(5*1)+(4*4)+(3*6)+(2*8)+(1*7)=175
175 % 10 = 5
So 197146-87-5 is a valid CAS Registry Number.
