113138-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113138-74-2 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 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 113138-74:
(8*1)+(7*1)+(6*3)+(5*1)+(4*3)+(3*8)+(2*7)+(1*4)=92
92 % 10 = 2
So 113138-74-2 is a valid CAS Registry Number.
