21339-38-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21339-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21339-38:
(7*2)+(6*1)+(5*3)+(4*3)+(3*9)+(2*3)+(1*8)=88
88 % 10 = 8
So 21339-38-8 is a valid CAS Registry Number.

Intramolecular electrophilic hydroarylation via Claisen rearrangement: synthesis of chromenes, heterothiochromenes and heterodihydrothiochromenes

Kenny, Rajesh S.,Mashelkar, Uday C.,Rane, Deepak M.,Bezawada, Dinesh K.

, p. 9280 - 9288 (2006)

We have designed and synthesized several basic and novel fused ring heterocycles by intramolecular hydroarylation with an efficiency and scope to develop intermediates of potential value. This method demonstrated consistent performance with arene-ene and arene-yne substrates of diverse structural features, including propargyl ethers, allyl thioethers, and propargyl thioethers resulting in 6-endo products.
