Check Digit Verification of cas no

The CAS Registry Mumber 37629-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,6,2 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 37629-77:
(7*3)+(6*7)+(5*6)+(4*2)+(3*9)+(2*7)+(1*7)=149
149 % 10 = 9
So 37629-77-9 is a valid CAS Registry Number.

Cyano Group Removal from Cyano-Promoted Aza-Diels-Alder Adducts: Synthesis and Structure-Activity Relationship of Phenanthroindolizidines and Phenanthroquinolizidines

Chang, Chi-Fen,Li, Chien-Fu,Tsai, Chia-Chen,Chuang, Ta-Hsien

supporting information, p. 638 - 641 (2016/03/01)

Phenanthroindolizidines and phenanthroquinolizidines were concisely synthesized by the reductive decyanization of cyano-promoted intramolecular aza-Diels-Alder cycloadducts followed by aryl-aryl coupling. Cyano groups were removed from α-aminoacrylonitriles via treatment with sodium borohydride in 2-propanol in almost quantitative yields; a possible mechanism was proposed and examined using D-labeling experiments. A systematic study of the effects of the phenanthrene substitution pattern on the anticancer activity against three human cancer cell lines was discussed. (Chemical Equation Presented).

Synthesis of phenanthro[9,10-b]indolizidin-9-ones, phenanthro[9,10-b] quinolizidin-9-one, and related benzolactams by Pd(OAc)2-catalyzed direct aromatic carbonylation

Yamashita, Satoshi,Kurono, Nobuhito,Senboku, Hisanori,Tokuda, Masao,Orito, Kazuhiko

supporting information; experimental part, p. 1173 - 1180 (2009/07/11)

Phenanthro[9,10-b]indolizidin-9-ones, phenanthro[9,10-b]-quinolizidin-9- one, and related benzolactams were synthesized by benzolactam ring formation using Pd(OAc)2-catalyzed direct aromatic carbonylation. This also constitutes a formal synthesis of the representative phenanthroindolizidine and -quinolizidine alkaloids (±)-tylophorine, (±)-antofine, and (±)-cryptopleurine. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.
