1240185-71-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240185-71-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,8 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1240185-71:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*8)+(3*5)+(2*7)+(1*1)=120
120 % 10 = 0
So 1240185-71-0 is a valid CAS Registry Number.
