125150-91-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125150-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,5 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125150-91:
(8*1)+(7*2)+(6*5)+(5*1)+(4*5)+(3*0)+(2*9)+(1*1)=96
96 % 10 = 6
So 125150-91-6 is a valid CAS Registry Number.

ATTEMPTED SIMMONS-SMITH REACTION ON α-OXOKETENE DITHIOACETALS: A NEW GENERAL ROUTE TO 3,4-SUBSTITUTED AND ANNELATED THIOPHENES

Thomas, Abraham,Singh, Gurdeep,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar

, p. 3093 - 3096 (1989)

A new general method for 3,4-substituted and annelated thiophenes through intramolecular cyclocondensation of a sulphonium ylid intermediate under Simmons-Smith reaction conditions on α-oxoketene dithioacetals has been reported.

Attempted Simmons-Smith reaction on α-oxoketene dithioacetals: A new general route to 3,4-substituted and annelated thiopenes

Bhat,Thomas,Ila,Junjappa

, p. 10377 - 10388 (2007/10/02)

A new general synthesis of 3- and 3,4-substituted 4a-q, 3,4-annelated 7a-d and condensed tricyclic 9a-e thiophenes has been developed through Simmons-Smith reaction of the respective α-oxoketene dithioacetals. Extension of the reaction of α-cinnamoylketene dithioacetals 10a-e and its higher enyl analogs 13a-d, 15a-c gave the corresponding 3-styryl 11a-e and 3-di- and trienyl 14a-d, 16a-c thiophenes in highly regioselective manner. A probable mechanism involving an unusual intramolecular aldol condensation of sulphonium ylid formed through carbenoid methylene insertion on divalent sulfur has been suggested.
