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.
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.
