Check Digit Verification of cas no

The CAS Registry Mumber 4277-64-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4277-64:
(6*4)+(5*2)+(4*7)+(3*7)+(2*6)+(1*4)=99
99 % 10 = 9
So 4277-64-9 is a valid CAS Registry Number.

The synthesis of the N-ethoxycarbonyl derivative of 5-azabicyclo[2.1.0]-pent-2-ene (Dewar pyrrole) - The first member of the parent ring-system

Warrener, Ronald N.,Amarasekara, Ananda S.,Russell, Richard A.

, p. 1519 - 1520 (2007/10/03)

N-Ethoxycarbonyl Dewar pyrrole 9, the first member of the parent ring, is formed via photofragmentation of 6 at -60°C and trapped as its adduct with 1,3-diphenylisobenzofuran 11; above this temperature, 9 is unstable and isomerises to N-ethoxycarbonylpyrrole 10.

The Chemistry of Acyl- and Sulphonyl-thionitroso Compounds

Meth-Cohn, Otto,Vuuren, Gerda van

, p. 245 - 250 (2007/10/02)

Thiophene S,N-ylides undergo cycloadditions with nucleophilic alkenes to give adducts with concomitant extrusion of acylthionitroso compounds.These new and highly reactive species may be trapped by dienes (to give thiazines by cycloaddition) or by enes (to give acylthiohydroxylamines by ene reaction).With suitable dienes such as isopropene and dimethylbutadiene, the ene reaction competes with the diene addition.In the absence of trap, ethyl thionitrosoformate in aromatic solvents yields bis(ethoxycarbonyl amino) sulphide, while with cyclopentadiene a 2:1 adduct, a rare example of a 1,3,2,4-dithiadiazine, is formed.Thiophene is shown to yield a transient S,N-ylide on treatment with ethoxycarbonylnitrene.

ARE THIOPHENES ATTACKED AT SULPHUR BY NITRENES?

Meth-Cohn, Otto,Vuuren, Gerda van

, p. 1105 - 1108 (2007/10/02)

Ethyl azidoformate is shown to attack a range of thiophenes at sulphur giving transient S,N-ylides which can be trapped with acenaphthylene as adducts; thiophene yields self-trapped products also.
