113308-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113308-59-1 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 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113308-59:
(8*1)+(7*1)+(6*3)+(5*3)+(4*0)+(3*8)+(2*5)+(1*9)=91
91 % 10 = 1
So 113308-59-1 is a valid CAS Registry Number.
