158503-49-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 158503-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158503-49:
(8*1)+(7*5)+(6*8)+(5*5)+(4*0)+(3*3)+(2*4)+(1*9)=142
142 % 10 = 2
So 158503-49-2 is a valid CAS Registry Number.

Direct arylation of substituted pyridines with arylboronic acids catalyzed by iron(II) oxalate

Huang, Yibo,Guan, Dan,Wang, Liang

, p. 1294 - 1298 (2015/02/05)

The direct arylation of substituted pyridines with several arylboronic acids has been developed. This transformation could proceed readily at ambient temperature using inexpensive reagents: iron(II) oxalate as a catalyst, potassium persulfate as a co-oxidant, which can afford the arylated products in mild to good yields. The mechanism is presumed to proceed through a nucleophilic radical addition to the pyridines with in situ reoxidation.

SYNTHESIS AND BIOLOGICAL ACTIVITIES OF NEW HMG-COA SYNTHASE INHIBITORS: 2-OXETANONES WITH A SIDE CHAIN CONTAINING BIPHENYL, TERPHENYL OR PHENYLPYRIDINE

Hashizume, Hirokazu,Ito, Hajime,Kanaya, Naoaki,Nagashima, Hajime,Usui, Hiroyuki,et al.

, p. 1551 - 1572 (2007/10/02)

A series of 1233A analogs containing biphenylyl, terphenylyl or phenylpyridyl groups in their side chain were synthesized and tested for the inhibitory activities against 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase and inhibition for the chol
