Check Digit Verification of cas no

The CAS Registry Mumber 294857-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,4,8,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 294857-25:
(8*2)+(7*9)+(6*4)+(5*8)+(4*5)+(3*7)+(2*2)+(1*5)=193
193 % 10 = 3
So 294857-25-3 is a valid CAS Registry Number.

Versatile synthesis of 3,4-b diheteropentalenes

Dey, Tanmoy,Navarathne, Daminda,Invernale, Michael A.,Berghorn, Ian D.,Sotzing, Gregory A.

supporting information; experimental part, p. 2089 - 2091 (2010/06/14)

We describe a new route for the synthesis of thieno[3,4-b]thiophene, alkyl derivatives thereof, seleno[3,4-b]thiophene, and thieno[3,4-b]furan made from inexpensive starting materials, such as thiophene-2-carboxylic acid and furan-2-carboxylic acid. Such fused heterocycles are of great interest for low band gap organic semiconductors and applications including OLEDs, organic photovoltaic cells, and electrochromics.

α,25-Dihydroxyvitamin D3 analogs featuring aromatic and heteroaromatic rings: Design, synthesis, and preliminary biological testing

Posner,Li,White,Vinader,Takeuchi,Guggino,Dolan,Kensler

, p. 4529 - 4537 (2007/10/03)

Aromatic compounds 2a-c, analogs of 1α,25-dihydroxyvitamin (calcitriol, 1), and heteroaromatic compounds 4a-c and 5a-c, analogs of 19-nor-1α,25- dihydroxyvitamin D3 (3), were designed to simulate the topology of their biologically potent parent
