Check Digit Verification of cas no

The CAS Registry Mumber 123852-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,5 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123852-08:
(8*1)+(7*2)+(6*3)+(5*8)+(4*5)+(3*2)+(2*0)+(1*8)=114
114 % 10 = 4
So 123852-08-4 is a valid CAS Registry Number.

Synthesis of branched monodisperse oligoethylene glycols and 19f mri-traceable biomaterials through reductive dimerization of azides

Chen, Shizhen,Jiang, Zhong-Xing,Li, Yu,Yang, Hao,Yang, Zhigang,Yuan, Yuan,Zhang, Huaibin,Zhang, Jing,Zhou, Xin

, p. 6778 - 6787 (2020/06/08)

Multifunctionalized and branched M-OEGs represent valuable PEGylation agents, linkers, and scaffolds in biomedicine. However, the tedious synthesis limited their availability and application. We herein present an azide reductive dimerization method for the convenient synthesis of aza-M-OEGs and derivatives, which provides easy access to a variety of multifunctionalized and branched M-OEGs in one step. With this method, hexa-arm M-OEGs with 54 symmetrical fluorines were synthesized in two steps as a water-soluble, self-assemble, 19F MRI sensitive, and biocompatible dendritic biomaterial.

Monodisperse perfluoro-polyethoxylated amphiphilic compounds with two-chain polar head - Preparation and properties

Selve,Ravey,Stebe,El Moudjahid,Moumni,Delpuech

, p. 411 - 428 (2007/10/02)

Monodisperse new surfactant molecules with a two-chain polyoxyethylene (EO) hydrophilic head and a perfluoroalkyl hydrophobic moiety linked together through an amide bond are synthesized by methods allowing large-scale production. Surface tension measurements (γ ~ 20 mN·m-1) show slow organization of the surfactant film at the water/air interface for longer fluorocarbon tail. Values of critical micellar concentrations and comparisons with monosubstituted amide surfactants are consistent with a high hydrophilicity of the amide function, a small influence of branching over hydrophilicity, and a hydrophobicity of each CF2 unit equivalent to 1.7 methylenes (in the analogous hydrogenated surfactants).
