Check Digit Verification of cas no

The CAS Registry Mumber 91388-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,8 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91388-23:
(7*9)+(6*1)+(5*3)+(4*8)+(3*8)+(2*2)+(1*3)=147
147 % 10 = 7
So 91388-23-7 is a valid CAS Registry Number.

Diarylrhodates as promising active catalysts for the arylation of vinyl ethers with grignard reagents

Iwasaki, Takanori,Miyata, Yoshinori,Akimoto, Ryo,Fujii, Yuuki,Kuniyasu, Hitoshi,Kambe, Nobuaki

, p. 9260 - 9263 (2014/07/21)

Anionic diarylrhodium complexes, generated by reacting [RhCl(cod)] 2 with 2 equiv of aryl Grignard reagents, were found to be effective active catalysts in cross-coupling reactions of vinyl ethers with aryl Grignard reagents, giving rise to the production of vinyl arenes. In this catalytic system, vinyl-O bonds were preferably cleaved over Ar-O or Ar-Br bonds. A lithium rhodate complex was isolated, and its crystal structure was determined by X-ray crystallography.
