40742-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40742-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,4 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40742-25:
(7*4)+(6*0)+(5*7)+(4*4)+(3*2)+(2*2)+(1*5)=94
94 % 10 = 4
So 40742-25-4 is a valid CAS Registry Number.

Universal chromogenic substrates for lipases and esterases

Grognux, Johann,Wahler, Denis,Nyfeler, Erich,Reymond, Jean-Louis

, p. 2981 - 2989 (2007/10/03)

Chromogenic mono- and diacyl-glycerol analogues were prepared and tested as substrates against lipases and esterases in a microtiter plate setup. Thirty-three enzyme samples were analyzed for activity at 100, 10, and 1 μg mL-1. The reaction rat
