Check Digit Verification of cas no

The CAS Registry Mumber 76929-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,2 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76929-37:
(7*7)+(6*6)+(5*9)+(4*2)+(3*9)+(2*3)+(1*7)=178
178 % 10 = 8
So 76929-37-8 is a valid CAS Registry Number.

Direct synthesis of polysubstituted 2-aminothiophenes by Cu(ii)-catalyzed addition/oxidative cyclization of alkynoates with thioamides

Ge, Li-Shi,Wang, Zheng-Lin,An, Xing-Lan,Luo, Xiaoyan,Deng, Wei-Ping

, p. 8473 - 8479 (2014/12/10)

A facile and direct synthetic method was developed for the construction of structurally important 2-aminothiophenes in moderate to excellent yields (up to 91%), via Cu(ii)-catalyzed addition/oxidative cyclization of readily available thioamides with alkynoates under an air atmosphere. This journal is

Two-carbon extension of N,N-disubstituted amides with bis(trimethylsilyl) thioketene affording N,N-disubstituted 3-oxothioamides

Tsuchiya, Tohru,Oishi, Akihiro,Shibuya, Isao,Taguchi, Yoichi,Honda, Kazumasa

, p. 1621 - 1622 (2007/10/03)

N,N-Disubstituted alkanamides cleanly react with bis(trimethylsilyl)thioketene to form N,N-disubstituted 2-trimethylsilyl-3-trimethylsilyloxyalk-2-enethioamides, which upon acid hydrolysis give N,N-disubstituted 3-oxoalkanethioamides.
