113849-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113849-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,4 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113849-91:
(8*1)+(7*1)+(6*3)+(5*8)+(4*4)+(3*9)+(2*9)+(1*1)=135
135 % 10 = 5
So 113849-91-5 is a valid CAS Registry Number.
