Check Digit Verification of cas no

The CAS Registry Mumber 1575-74-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1575-74:
(6*1)+(5*5)+(4*7)+(3*5)+(2*7)+(1*4)=92
92 % 10 = 2
So 1575-74-2 is a valid CAS Registry Number.

Synthesis of S-(+)-4-methyl-3-heptanone, the principal alarm pheromone of Atta texana, and its enantiomer

Riley,Silverstein

, p. 1171 - 1174 (1974)

The principal alarm pheromone of Atta texana S-(+)-4-methyl-3-heptanone, and its enantiomer have been prepared synthetically in high optical purity.

Synthesis of 5-[(Pentafluorosulfanyl)methyl]-γ-butyrolactones via a Silver-Promoted Intramolecular Cyclization Reaction

Roudias, Majdouline,Gilbert, Audrey,Paquin, Jean-Fran?ois

, p. 6655 - 6665 (2019/11/03)

The synthesis of 5-[(pentafluorosulfanyl)methyl]-γ-butyrolactones bearing different substituents at position 3 or 4 is reported. A silver-promoted intramolecular cyclization of substituted 4-chloro-5-(pentafluorosulfanyl)pentanoic acids allows the preparation of the substituted SF5-containing γ-butyrolactones in up to 96 % yield.

Direct oxidative lactonization of alkenoic acids mediated solely by NaIO4: Beyond a simple oxidant

Kang, Yan-Biao,Chen, Xian-Min,Yao, Chuan-Zhi,Ning, Xiao-Shan

supporting information, p. 6193 - 6196 (2016/05/19)

Triflic acid-catalyzed direct oxidative lactonization of alkenoic acids mediated solely by NaIO4 without halogen salts is described. Sodium periodate works not only as an oxidant, but also as an active reagent and directly mediates the lactonization. A new cheap, green, and practical oxidative lactonization approach has been developed using NaIO4 as the sole reagent.
