1033591-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1033591-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,5,9 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1033591-49:
(9*1)+(8*0)+(7*3)+(6*3)+(5*5)+(4*9)+(3*1)+(2*4)+(1*9)=129
129 % 10 = 9
So 1033591-49-9 is a valid CAS Registry Number.
