Check Digit Verification of cas no
The CAS Registry Mumber 130-14-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130-14:
(5*1)+(4*3)+(3*0)+(2*1)+(1*4)=23
23 % 10 = 3
So 130-14-3 is a valid CAS Registry Number.

Synthesis of Aromatic and Olefinic Sodium Sulfonates by Electrophilic Destannylation with Trimethylsilyl Chlorosulfonate
Niestroj, Michael,Lube, Andreas,Neumann, Wilhelm P.
, p. 575 - 580 (2007/10/02)
A mild and effective method for the preparation of a variety of aromatic, olefinic, and acetylenic sodium sulfonates is described.The reaction of trialkylaryl- (2a-k) and -heteroarylstannanes (4a-d), bis-(1-alkenyl)dibutylstannanes (6a-f), or trialkylakynylstannanes with trimethylsilyl chlorosulfonate (1) followed by hydrolysis with aqueous NaHCO3 provides the sodium sulfonates in an ipso-specific and in the case of vinylic stannanes stereospecific manner.A comparision of the reactivity of stannylated and silylated olefinic compounds 13 and 14 underlines the greater leaving ability of the stannyl moiety.The in situ preparation of the stannanes makes it possible to apply the synthetic method to natural products such as N-substituted apocodeine (17). - Key Words: Electrophilic aromatic substitution/ Electrophilic vinylic substitution/ Trialkylstannanes, application of/ Arylsulfonates, sodium salts of/ Vinylsulfonates, sodium salts of
