113306-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113306-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,0 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 113306-95:
(8*1)+(7*1)+(6*3)+(5*3)+(4*0)+(3*6)+(2*9)+(1*5)=89
89 % 10 = 9
So 113306-95-9 is a valid CAS Registry Number.
