Check Digit Verification of cas no

The CAS Registry Mumber 205756-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,7,5 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 205756-59:
(8*2)+(7*0)+(6*5)+(5*7)+(4*5)+(3*6)+(2*5)+(1*9)=138
138 % 10 = 8
So 205756-59-8 is a valid CAS Registry Number.

Experimental and Computational Studies on Rh(I)-Catalyzed Reaction of Siloxyvinylcyclopropanes and Diazoesters

Feng, Sheng,Wang, Kang,Ping, Yifan,Wang, Jianbo

supporting information, p. 21032 - 21039 (2020/12/21)

The Rh(I)-catalyzed reaction of siloxyvinylcyclopropanes and diazoesters leads to the formation of siloxyvinylcyclobutane and 1,4-diene derivatives. With [Rh(cod)Cl]2 as the catalyst, the formation of 1,4-diene was favored over the formation of siloxyvinylcyclobutane. By changing the catalyst to [Rh(cod)2OTf], siloxyvinylcyclobutane derivatives are formed with excellent chemoselectivities and in moderate to good yields. The alkene products are also obtained as single E configured isomers. A detailed mechanism for this transformation is proposed on the basis of mechanistic experiments and DFT calculations. The effect of catalysts on the chemoselectivity of these reactions is also examined computationally.
