16732-86-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16732-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,3 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16732-86:
(7*1)+(6*6)+(5*7)+(4*3)+(3*2)+(2*8)+(1*6)=118
118 % 10 = 8
So 16732-86-8 is a valid CAS Registry Number.

REDUCTIVE REMOVAL OF ALLYLIC FUNCTIONAL GROUPS BY NICKEL BORIDE

Sarma, D. N.,Sharma, R. P.

, p. 2581 - 2584 (1985)

Reductive removal of an allylic functional group proceeds most easily and efficiently with nickel boride as the bond being cleaved becomes a better leaving group ( e.g.OCH3OHOSiMe3OCOCH3OCOCF3 )

Dephosphorylation of Cyano Diethyl Phosphates by Reduction with Lithium-Liquid Ammonia: An Efficient Method for Conversion of Carbonyl Compounds into Nitriles

Yoneda, Ryuji,Osaki, Takahiro,Harusawa, Shinya,Kurihara, Takushi

, p. 607 - 610 (2007/10/02)

Cyano diethyl phosphate derivatives of aromatic carbonyl compounds and α,β-unsaturated ketones were successively dephosphorylated by reduction with lithium in liquid ammonia followed by treatment with isoprene or alkyl halides to give β,γ-unsaturated nitriles or α-alkyl-β,γ-unsaturated nitriles in moderate to good yields.

Acid-catalysed Rearrangements of Steroid Alkenes. Part 2. A Re-investigation of the Backbone Rearrangement of Cholest-5-ene

Peakman, Torren M.,Ellis, Karen,Maxwell, James R.

, p. 1071 - 1076 (2007/10/02)

Backbone rearrangement of cholest-5-ene (1) with boron trifluoride-diethyl ether gives, in addition to the well known diacholest-13(17)-enes (4a,b), their 10β counterparts (6a,b) as minor products.With anhydrous toluene-p-sulphonic acid-acetic acid, additional products include components also isomeric at C-10 and C-20 and having a spiro C/D ring junction.A proposed scheme for the rearrangement is given.
