113139-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113139-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,1,3 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 113139-22:
(8*1)+(7*1)+(6*3)+(5*1)+(4*3)+(3*9)+(2*2)+(1*2)=83
83 % 10 = 3
So 113139-22-3 is a valid CAS Registry Number.
