31236-97-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31236-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,3 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31236-97:
(7*3)+(6*1)+(5*2)+(4*3)+(3*6)+(2*9)+(1*7)=92
92 % 10 = 2
So 31236-97-2 is a valid CAS Registry Number.

Synthesis of 2,3-dihydro-1-phenylbenzo[b]phosphole (1-phenylphosphindane) and its use as a mechanistic test in the asymmetric appel reaction: Decisive evidence against involvement of pseudorotation in the stereoselecting step

Carr, Damien J.,Kudavalli, Jaya Satyanarayana,Dunne, Katherine S.,Mueller-Bunz, Helge,Gilheany, Declan G.

, p. 10500 - 10505 (2013/11/06)

Racemic 2,3-dihydro-1-phenylbenzo[b]phosphole was obtained by reduction of 1-phenylbenzo[b]phosphole-1-oxide, itself derived by ring-closing metathesis of phenylstyrylvinylphosphine oxide. The title compound was then reoxidized under asymmetric Appel cond

A Versatile Synthetic Route to 1-Benzometalloles involving the First Examples of Several C-Unsubstituted Benzometalloles

Kurita, Jyoji,Ishii, Makoto,Yasuike, Shuji,Tsuchiya, Takashi

, p. 1309 - 1310 (2007/10/02)

The group 14 (Si, Ge, Sn), group 15 (P, As, Sb, Bi) and group 16 (S, Se, Te) (2-trimethylsilyl)-1-benzometalloles 5 have been prepared from phenylacetylene via three steps and converted into the corresponding C-unsubstituted benzometalloles 7 by detrimethylsilylation.
