Check Digit Verification of cas no

The CAS Registry Mumber 71150-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,5 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71150-68:
(7*7)+(6*1)+(5*1)+(4*5)+(3*0)+(2*6)+(1*8)=100
100 % 10 = 0
So 71150-68-0 is a valid CAS Registry Number.

Propylphosphonic anhydride (T3P)-mediated one-pot rearrangement of carboxylic acids to carbamates

Augustine, John Kallikat,Bombrun, Agnes,Mandal, Ashis Baran,Alagarsamy, Padma,Atta, Rajendra Nath,Selvam, Panneer

experimental part, p. 1477 - 1483 (2011/06/11)

A simple one-pot conversion of carboxylic acids to carbamates is achieved by propylphosphonic anhydride (T3P) in combination with azidotrimethylsilane and an alcohol via the Curtius rearrangement. Besides diverse primary to tertiary alcohols, t

Synthesis of aza-, oxa-, and thiabicyclo[3.1.0]hexane heterocycles from a common synthetic intermediate

Renslo, Adam R.,Gao, Hongwu,Jaishankar, Priyadarshini,Venkatachalam, Revathy,Gordeev, Mikhail F.

, p. 2627 - 2630 (2007/10/03)

(Chemical Equation Presented) An efficient and stereospecific approach to the synthesis of structurally constrained aza-, oxa-, and thiabicyclo[3.1.0] hexane heterocycles has been achieved through application of the intramolecular cyclopropanation reactio

Palladium-catalyzed intermolecular coupling of aryl halides and amides

Yin, Jingjun,Buchwald, Stephen L.

, p. 1101 - 1104 (2007/10/03)

The first general intermolecular C-N bond-forming reactions between aryl halides and amides were realized using a palladium catalyst with Xantphos as the ligand. Aryl triflates, carbamates, and sulfonamides are also viable substrates for the amidations, which proceed at 45-110 °C with 1-4 mol% of Pd catalyst in 66-99% yields and exhibit good functional group compatibility.
