Benzenemethanethiol, a-methylene-, also known as 1-(phenylmethylene)-2-propanethiol or α-methylenebenzenemethanethiol, is an organic compound with the chemical formula C9H10S. It is a colorless to pale yellow liquid with a strong, pungent odor. Benzenemethanethiol, a-methylene- is characterized by the presence of a benzene ring, a methylene group (-CH2-), and a methanethiol group (-SH). It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its reactive nature, it is typically handled with care and stored under controlled conditions to prevent unwanted reactions or decomposition.

Check Digit Verification of cas no

The CAS Registry Mumber 91786-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,8 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91786-08:
(7*9)+(6*1)+(5*7)+(4*8)+(3*6)+(2*0)+(1*8)=162
162 % 10 = 2
So 91786-08-2 is a valid CAS Registry Number.

REACTIVE DOUBLE BOND SYSTEMS VIA (3+2) CYCLOREVERSION OF HETEROCYCLES

Schaumann, Ernst

, p. 995 - 1008 (2007/10/02)

After deprotonation, saturated five-membered heterocyclic rings give a facile (3+2) cycloreversion.This approach is employed in syntheses of ketenes, thioaldehydes, thioketones, thioketenes and a thioquinone at low temperature.These highly reactive double-bond systems are usually trapped in situ using (2+2), (2+3), or (2+4) cycloadditions to give various types of heterocycles.
