111738-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111738-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111738-22:
(8*1)+(7*1)+(6*1)+(5*7)+(4*3)+(3*8)+(2*2)+(1*2)=98
98 % 10 = 8
So 111738-22-8 is a valid CAS Registry Number.

2-Oxo-1,3-dioxoles as specific substrates for measurement of arylesterase activity
Kawai,Sakamoto,Taguchi,Kitamura,Sotomura,Tsukamoto
, p. 1422 - 1425 (2007/10/02)
Various 4-arylthiomethyl-2-oxo-1,3-dioxole derivatives IIIa-o were synthesized. Their hydrolysis rates by arylesterase (EC 3.1.1.2) and cholinesterase (EC 3.1.1.8) in human serum were evaluated. Some of them were not hydrolyzed by cholinesterase, but were
