1174209-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174209-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,2,0 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1174209-71:
(9*1)+(8*1)+(7*7)+(6*4)+(5*2)+(4*0)+(3*9)+(2*7)+(1*1)=142
142 % 10 = 2
So 1174209-71-2 is a valid CAS Registry Number.
