Check Digit Verification of cas no

The CAS Registry Mumber 19156-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,5 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19156-49:
(7*1)+(6*9)+(5*1)+(4*5)+(3*6)+(2*4)+(1*9)=121
121 % 10 = 1
So 19156-49-1 is a valid CAS Registry Number.

Ethyl 2-Aminothiophene-3-Carboxylates in the Synthesis of Isomeric Thienopyridines

Pokhodylo,Shyyka,Obushak

, p. 1748 - 1755 (2015/02/05)

A convenient method for the synthesis of thieno[3,2-c]pyridinones was developed. A number of thiophene derivatives was prepared, and the possibility of using thiophene desamino derivatives for the design of potentially biologically active molecules was demonstrated.

Thiol mediated 5-(π-endo)ortho vinyl radical cyclizations

Montevecchi, Pier Carlo,Navacchia, Maria Luisa

, p. 201 - 219 (2007/10/03)

The radical reaction of benzenethiol with alkynes 1a-o carried out at 154 °C affords a mixture of thiol/alkyne adduct 3 and benzothiophene 5, deriving from vinyl radical intermediates 2 through hydrogen abstraction and 5-(π-endo)(orthocyclization onto the

Thiol radical addition to alkynes. Sulfanyl radical addition and hydrogen atom abstraction relative reaction rates

Melandri, Daniela,Montevecchi, Pier Carlo,Navacchia, Maria Luisa

, p. 12227 - 12236 (2007/10/03)

2-(Toluenesulfanyl)- 1 and 2-(benzenesulfanyl)-phenylacetylene 10 reacted with benzenethiol and toluenethiol, respectively, in the presence of AIBN at 84 and 154°C to give products deriving from vinyl radicals 2 which undergo hydrogen abstraction reaction
