113116-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113116-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,1,1 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113116-41:
(8*1)+(7*1)+(6*3)+(5*1)+(4*1)+(3*6)+(2*4)+(1*1)=69
69 % 10 = 9
So 113116-41-9 is a valid CAS Registry Number.
