1175242-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1175242-70-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,5,2,4 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1175242-70:
(9*1)+(8*1)+(7*7)+(6*5)+(5*2)+(4*4)+(3*2)+(2*7)+(1*0)=142
142 % 10 = 2
So 1175242-70-2 is a valid CAS Registry Number.
