Check Digit Verification of cas no

The CAS Registry Mumber 77123-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,2 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77123-56:
(7*7)+(6*7)+(5*1)+(4*2)+(3*3)+(2*5)+(1*6)=129
129 % 10 = 9
So 77123-56-9 is a valid CAS Registry Number.

A copper (II) (II) composite chlorinating agent and copper-based composite chlorinating agent synthesis of 1-chloro-2-aryl acetylene method

-

Paragraph 0023; 0132; 0133, (2016/11/24)

The invention discloses a copper (II) composite chlorinating agent and a method for synthesizing 1-chlorine-2-aryl acetylene based on the copper (II) composite chlorinating agent. The structural formula of the copper (II) composite chlorinating agent is CuCl2.xNaCl.yAl2O3. The chlorinating agent is applicable to chlorination of various substituted aryl acetylene substrates, and is high in universality; the chlorinating agent can directly carry out chlorination reaction on aryl acetylene so as to obtain a 1-chlorine-2-aryl acetylene product; the method is mild in reaction condition, 1-chlorine-2-aryl acetylene can be synthesized with high yield and high selectivity, and the production cost of the 1-chlorine-2-aryl acetylene derivative is greatly lowered.

A one-pot allylation-hydrostannation sequence with recycling of the intermediate tin waste

Ghosh, Banibrata,Amado-Sierra, Maria Del Rosario I.,Holmes, Daniel,Maleczka, Robert E.

supporting information, p. 2318 - 2321 (2014/05/20)

A one-pot allylation and hydrostannation of alkynals where the tin byproduct formed in the first step of the reaction is recycled and used in the second step of the sequence is presented. Specifically, a BF3· OEt2-promoted allylstannation of the aldehyde moiety in the alkynal is followed by the introduction of polymethylhydrosiloxane (PMHS) and catalytic B(C6F5)3, which convert the tin byproduct of the allylation into Bu3SnH, which then hydrostannates the alkyne in the molecule. 119Sn and 11B NMR data suggest an organotin fluoride species is formed during the allylation step and involved in the tin recycling step.
