1165931-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1165931-71-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,5,9,3 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1165931-71:
(9*1)+(8*1)+(7*6)+(6*5)+(5*9)+(4*3)+(3*1)+(2*7)+(1*1)=164
164 % 10 = 4
So 1165931-71-4 is a valid CAS Registry Number.
