Check Digit Verification of cas no

The CAS Registry Mumber 1554261-67-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,4,2,6 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1554261-67:
(9*1)+(8*5)+(7*5)+(6*4)+(5*2)+(4*6)+(3*1)+(2*6)+(1*7)=164
164 % 10 = 4
So 1554261-67-4 is a valid CAS Registry Number.

Tetrabutylammonium Iodide Mediated Synthesis of β-Alkoxy Sulfides and Vinyl Sulfones by Using Benzenesulfonyl Chlorides as the Sulfur Sources under Acidic or Alkaline Conditions

Wang, Dingyi,Zhang, Rongxing,Lin, Sen,Yan, Zhaohua,Guo, Shengmei

, p. 2003 - 2008 (2016)

The tetrabutylammonium iodide (TBAI)-promoted generation of sulfur-containing compounds from benzenesulfonyl chlorides and alkenes is described. Under acidic condition, a wide range of β-alkoxy sulfides were obtained in good to excellent yields, whereas under alkaline conditions, various vinyl sulfones were produced in moderate to good yields. A novel preparation of (E)-β-iodovinyl sulfones was achieved through direct difunctionalization of alkynes with benzenesulfonyl chlorides and TBAI.

Three-component oxysulfenylation reaction: Two simple and convenient approaches to β-alkoxy sulfides

Wang, Dingyi,Zhang, Rongxing,Ning, Wei,Yan, Zhaohua,Lin, Sen

, p. 5136 - 5140 (2016/06/14)

An unprecedented method for the synthesis of β-alkoxy sulfides via a NaI/HBr-mediated three-component oxysulfenylation reaction of alkenes with arylsulfinic acids and alcohols is reported. Furthermore, I2-promoted oxysulfenylation of alkenes using sodium arylsulfinates instead of arylsulfinic acids to synthesise various β-alkoxy sulfides is also described.

Iodine-catalyzed three-component oxysulfenylation of alkenes with sulfonyl hydrazides and alcohols

Yang, Fu-Lai,Wang, Fu-Xiang,Wang, Ting-Ting,Wang, Yi-Jie,Tian, Shi-Kai

supporting information, p. 2111 - 2113 (2014/02/14)

An unprecedented three-component oxysulfenylation reaction of alkenes with sulfonyl hydrazides and alcohols has been developed in the presence of 20 mol% iodine to give a range of structurally diverse β-alkoxy sulfides in good to excellent yields. The Royal Society of Chemistry.
