Check Digit Verification of cas no

The CAS Registry Mumber 130847-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,4 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130847-23:
(8*1)+(7*3)+(6*0)+(5*8)+(4*4)+(3*7)+(2*2)+(1*3)=113
113 % 10 = 3
So 130847-23-3 is a valid CAS Registry Number.

C-Glycoside Synthesis via Glycal Alkylation by Olefinic Derivatives

Herscovici, Jean,Muleka, Kipamga,Boumaiza, Lotfi,Antonakis, Kostas

, p. 1995 - 2009 (2007/10/02)

Treatment of peracylated glycals with olefins in the presence of Lewis acids gave 2,3-unsaturated C-glycosides in good to excellent yields.The reaction was completely regioselective and showed a high degree of stereoselectivity leading mostly to the α-isomer.Generally the addition gave the C-glycoside with an unsaturated aglycone.However, with methylenecyclobutane and 1,1 disubstituted linear olefins halogeno derivatives were recovered.The reaction was also performed with acetylated 2-hydroxy glycals.In these conditions keto unsaturated α-C-glycosides were isolated.
