Check Digit Verification of cas no

The CAS Registry Mumber 90764-57-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,6 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90764-57:
(7*9)+(6*0)+(5*7)+(4*6)+(3*4)+(2*5)+(1*7)=151
151 % 10 = 1
So 90764-57-1 is a valid CAS Registry Number.

Rhodium-Catalyzed Generation of Anhydrous Hydrogen Iodide: An Effective Method for the Preparation of Iodoalkanes

Zeng, Chaoyuan,Shen, Guoli,Yang, Fan,Chen, Jingchao,Zhang, Xuexin,Gu, Cuiping,Zhou, Yongyun,Fan, Baomin

, p. 6859 - 6862 (2018)

The preparation of anhydrous hydrogen iodide directly from molecular hydrogen and iodine using a rhodium catalyst is reported for the first time. The anhydrous hydrogen iodide generated was proven to be highly active in the transformations of alkenes, phenyl aldehydes, alcohols, and cyclic ethers to the corresponding iodoalkanes. Therefore, the present methodology not only has provided convenient access to anhydrous hydrogen iodide but also offers a practical preparation method for various iodoalkanes in excellent atom economy.

Selective C(sp3)?H and C(sp2)?H Fluorination of Alcohols Using Practical Auxiliaries

Mao, Yang-Jie,Lou, Shao-Jie,Hao, Hong-Yan,Xu, Dan-Qian

supporting information, p. 14085 - 14089 (2018/10/15)

Selective introduction of fluorine into molecules by the cleavage of inert C?H bonds is of central academic and synthetic interest, yet remains challenging. Given the central role of alcohols in organic chemistry as the most ubiquitous building blocks, a

Method for the Preparation of Iodoalkanes

-

Paragraph 0036, (2017/08/07)

The present invention relates to an atom economic procedure of preparing iodoalkanes by hydroiodination of alkenes. In particular the present method features the generation of anhydrous hydrogen iodide from atomic hydrogen and iodine in situ by using transition metal precursor and phosphine ligandcatalyst.
