1033384-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1033384-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,3,8 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1033384-71:
(9*1)+(8*0)+(7*3)+(6*3)+(5*3)+(4*8)+(3*4)+(2*7)+(1*1)=122
122 % 10 = 2
So 1033384-71-2 is a valid CAS Registry Number.
