1032-16-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1032-16-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,3 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1032-16:
(6*1)+(5*0)+(4*3)+(3*2)+(2*1)+(1*6)=32
32 % 10 = 2
So 1032-16-2 is a valid CAS Registry Number.

Mechanistic studies of deoxygenation of steroidal ring-D 16,17-ketols with trimethylsilyl iodide

Nagaoka, Masao,Nagasawa, Etsuko,Sato, Sadao,Numazawa, Mitsuteru

, p. 548 - 553 (2007/10/03)

Deoxygenation reaction of steroidal 16,17-ketols 1, 2 and 6 as well as their silyl ethers 3 and 7 and 16- and 17-iodoketone analogs 11, 12, and 14 with trimethylsilyl iodide (TMSI) or HI under various conditions was examined. The results indicate that the deoxygenation producing 16- and 17- ketones 9 and 8 proceeds through multiple reaction pathways; a direct iodination of a siloxy group of the ketol silyl ethers by iodide ion to give the iodoketones (path b), addition of TMSI to a carbonyl group of the ketol silyl ethers to yield diiodo derivatives 22 and 23 through iodo-bis-TMS compounds 20 and 21 (path a), and cleavage of ether bond of dimers 15-18 initially produced are, at least, involved. In these sequences, rearrangement of the 16-ketols 1 and 2 to the 17 β-ketol 6 also plays a significant role. The yields of the ketones 9 and 8 and their relative amounts would be dependent on the relative importance of each pathway in the reaction.
