1143505-17-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1143505-17-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,3,5,0 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1143505-17:
(9*1)+(8*1)+(7*4)+(6*3)+(5*5)+(4*0)+(3*5)+(2*1)+(1*7)=112
112 % 10 = 2
So 1143505-17-2 is a valid CAS Registry Number.
