Check Digit Verification of cas no

The CAS Registry Mumber 1442636-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,2,6,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1442636-40:
(9*1)+(8*4)+(7*4)+(6*2)+(5*6)+(4*3)+(3*6)+(2*4)+(1*0)=149
149 % 10 = 9
So 1442636-40-9 is a valid CAS Registry Number.

Facile and versatile synthesis of alkyl and aryl isothiocyanates by using triphosgene and cosolvent

Liu, Pengfei,Li, Chunyan,Zhang, Jingwei,Xu, Xiaoyong

, p. 3342 - 3351 (2013)

A mild and efficient method for the conversion of alkyl and aryl amines to isothiocyanates via dithiocarbamates has been developed using (CH 3)2CO-CS2 as co-solvent and triphosgene as dehydrosulfurization reagent. High yields, mild reaction conditions and excellent functional group compatibility make it become a versatile synthetic method for the preparation of isothiocyanates compared with reported methods.

Synthesis, structure-activity relationship and binding mode analysis of 4-thiazolidinone derivatives as novel inhibitors of human dihydroorotate dehydrogenase

Zeng, Fanxun,Qi, Tiantian,Li, Chunyan,Li, Tingfang,Li, Honglin,Li, Shiliang,Zhu, Lili,Xu, Xiaoyong

supporting information, p. 1297 - 1302 (2017/07/07)

A series of 4-thiazolidinone derivatives were synthesized and evaluated as novel human dihydroorotate dehydrogenase (hDHODH) inhibitors. Compounds 26 and 31 displayed IC50 values of 1.75 and 1.12 μM, respectively. The structure-activity relationship was summarized. Further binding mode analysis revealed that compound 31 could form a hydrogen bond with Tyr38 and a water-mediated hydrogen bond with Ala55, which may be necessary for maintaining the bioactivities of the compounds in this series. Further structural optimization of the para- or meta-position of the phenyl group at R will lead to the identification of more potent hDHODH inhibitors.
