Check Digit Verification of cas no

The CAS Registry Mumber 10312-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,1 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10312-40:
(7*1)+(6*0)+(5*3)+(4*1)+(3*2)+(2*4)+(1*0)=40
40 % 10 = 0
So 10312-40-0 is a valid CAS Registry Number.

Substitution reactions of 2-phenylsulphonyl-piperidines and -pyrrolidines with carbon nucleophiles: Synthesis of the pyrrolidine alkaloids norruspoline and ruspolinone

Brown, Dearg S.,Charreau, Philippe,Hansson, Thomas,Ley, Steven V.

, p. 1311 - 1328 (2007/10/02)

Several 2-phenylsulphonyl-piperidines and -pyrrolidines were prepared from the corresponding N-acyl aminals by treatment with benzenesulphinic acid. On reaction with various carbon nucleophiles these sulphones gave good yields of substitution products. Typical nucleophiles used in these studies were organometallic reagents derived from Grignard reagents and zinc halide together with silyl enol ethers, silyl ketene acetals, allylsilanes and trimethylsilyl cyanide in the presence of a Lewis acid. These methods were employed in the synthesis of two natural product alkaloids; Norruspoline (38) and Ruspolinone (40).

APPLICATIONS OF THE THERMAL ENE REACTION OF ALDEHYDE t-BUTYL- AND PHENYL- HYDRAZONES

Baldwin, Jack E.,Adlington, Robert M.,Jain, Ashok U.,Kolhe, Jayant N.,Perry, Matthew W. D.

, p. 4247 - 4252 (2007/10/02)

The Thermal Ene reaction of aldehyde t-butyl- and phenyl- hydrazones with enophiles gave C-trapped azo-adducts which can be diverted into synthetically useful γ-keto-esters, γ-keto-nitriles, γ-alkyl-2-pyrrolidones, and γ-amino-esters.
