Check Digit Verification of cas no

The CAS Registry Mumber 94413-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,1 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94413-73:
(7*9)+(6*4)+(5*4)+(4*1)+(3*3)+(2*7)+(1*3)=137
137 % 10 = 7
So 94413-73-7 is a valid CAS Registry Number.

A telescoped protocol for the synthesis of new pyrrolo [3,4-d]pyridazinones by cascade reactions

Bonacorso, Helio G.,Libero, Francieli M.,Dal Forno, Gean M.,Pittaluga, Everton P.,Porte, Liliane M.F.,Martins, Marcos A.P.,Zanatta, Nilo

supporting information, p. 5190 - 5195 (2015/08/19)

A new one-pot method, for the synthesis of polysubstituted pyrrolo[3,4-d]pyridazinones, is presented. The protocol consists in cascade reactions performed in the same media: (i) the thermal in situ pyrrole formation by the reaction of vinyl azides with 1,

Gold(I)-catalyzed rearrangement of alkynylaziridine indoles for the synthesis of spiro-tetrahydro-β-carbolines

Yang, Yan-Fang,Li, Lian-Hua,He, Yu-Tao,Luo, Jian-Yi,Liang, Yong-Min

supporting information, p. 702 - 707 (2014/02/14)

Functionalized spiro-tetrahydro-β-carbolines were formed by an efficient gold(I)-catalyzed rearrangement reaction of alkynylaziridine indoles. The reaction involved a Friedel-Crafts type intramolecular reaction of alkynylaziridine indoles, following by hydroamination of aminoallene intermediate.

AMINO ACIDS AS SYNTHONS FOR HETEROCYCLES. FORMATION OF 1,2,4-TRIAZINE DERIVATIVES

Smodis, Janez,Zupet, Rok,Petric, Andrej,Stanovnik, Branko,Tisler, Miha

, p. 393 - 405 (2007/10/02)

Transformation of the amino group of amino acids into an amidine and subsequent treatment with hydrazine leads to 1,2,4-triazine-6(1H)-ones.The method described is a new synthetic approach.Unsaturated amino acids gave imidazol-5-one derivatives after the
