3011-82-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3011-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,1 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3011-82:
(6*3)+(5*0)+(4*1)+(3*1)+(2*8)+(1*2)=43
43 % 10 = 3
So 3011-82-3 is a valid CAS Registry Number.

Single-stage synthesis of alkyl-H-phosphinic acids from elemental phosphorus and alkyl bromides

Gusarova, Nina K.,Sutyrina, Anastasiya O.,Kuimov, Vladimir A.,Malysheva, Svetlana F.,Belogorlova, Natalia A.,Volkov, Pavel A.,Trofimov, Boris A.

, p. 328 - 330 (2019/06/13)

Elemental phosphorus (red or white) reacts with alkyl bromides at 60–62 °C in the phase-transfer catalytic system KOH/H2O/PhMe/Et3BnNCl to afford alkyl-H-phosphinic acids in up to 47% yield.

SUPERBASE-INDUCED GENERATION OF PHOSPHIDE AND PHOSPHINITE IONS AS APPLIED IN ORGANIC SYNTHESIS

Trofimov, B. A.,Gusarova, N. K.,Malysheva, S. F.,Rakhmatulina, T. N.,Voronkov, M. G.,et al.

, p. 271 - 274 (2007/10/02)

A series of new direct reactions of red phosphorus (or white) with organyl halides, alkenes and acetylenes have been developed.Reactions occur in superbasic systems, such as alkali metal hydroxide-dipolar aprotic complexing solvent (DMSO, HMPA) or under phase-transfer conditions to afford earlier inaccessible triorganylphosphines and -phosphine oxides including unsaturated ones in good yield.
