Check Digit Verification of cas no

The CAS Registry Mumber 849455-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,4,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 849455-40:
(8*8)+(7*4)+(6*9)+(5*4)+(4*5)+(3*5)+(2*4)+(1*0)=209
209 % 10 = 9
So 849455-40-9 is a valid CAS Registry Number.

Synthesis of novel thiazolyl-pyrimidines and their anticancer activity in vitro

Shi, Hai-Bo,Li, Hai-Bo,Lu, Kong-Qin,Zhu, Xia-Re,Hu, Wei-Xiao,Pei, Wen

scheme or table, p. 675 - 683 (2012/06/01)

A series of novel compounds 7-43 were prepared via the condensation of enaminones 4a-h and the guanidines carbonate 6a-f. The structures of these newly synthesized compounds were confirmed by 1H-NMR, MS, EA and IR. All the compounds were tested for their cytotoxic activity in vitro against human cancer cell lines including Ishikawa, A549, BEL-7404, SPC-A-01 and SGC-7901. Most of them showed moderate cytotoxic against the tested cell lines. Among them, the most potent compounds 9 and 30 exhibited more efficient activity against Ishikawa, A549. Thiazolyl-pyrimidines were synthesized by the general pyrimidine condensation of Bredereck and their in-vitro anticancer activities were evaluated. Copyright

Synthesis and anticancer evaluation of thiazolyl-chalcones

Shi, Hai-Bo,Zhang, Shi-Jie,Ge, Qiu-Fu,Guo, Dian-Wu,Cai, Chao-Ming,Hu, Wei-Xiao

experimental part, p. 6555 - 6559 (2010/12/19)

Thirty-seven (E)-1-(4-methyl-2-arylaminothiazol-5-yl)-3-arylprop-2-en-1- ones were synthesized via Claisen-Schmidt condensation of 1-(4-methyl-2- (arylamino)thiazol-5-yl)ethanone with the corresponding arylaldehydes. All these thiazolyl-chalcones were cha
