113811-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113811-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,1 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113811-91:
(8*1)+(7*1)+(6*3)+(5*8)+(4*1)+(3*1)+(2*9)+(1*1)=99
99 % 10 = 9
So 113811-91-9 is a valid CAS Registry Number.
