Check Digit Verification of cas no

The CAS Registry Mumber 139950-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,5 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139950-96:
(8*1)+(7*3)+(6*9)+(5*9)+(4*5)+(3*0)+(2*9)+(1*6)=172
172 % 10 = 2
So 139950-96-2 is a valid CAS Registry Number.

Sm/Sml2/TiCl4(cat.) system promoted direct alkylidenating reaction of ketones with gem-dibromomethyl sulfones: A new method for preparation of alkylidene sulfones

Liu,Zhang,Liu

, p. 472 - 473 (2007/10/03)

Alkylidene sulfones were prepared in moderate to good yields via direct alkylidenating reaction of ketones with geminal dibromomethyl sulfones promoted by the Sm/Sml2 system in the presence of a catalytic amount of TiCl4 under mild conditions.

"Syn-Effect" in the Conversion of (E)-Vinylic Sulfones to the Corresponding Allylic Sulfones

Hirata, Takaki,Sasada, Yoshihiro,Ohtani, Takashi,Asada, Takahiro,Kinoshita, Hideki,et al.

, p. 75 - 96 (2007/10/02)

It was found that (E)-vinylic sulfones preferentially afford (Z)-allylic sulfones as kinetically-controlled products by treatment with a base under mild conditions, while (Z)-vinylic sulfones give (E)-allylic sulfones.Such stereochemical relationship was

Addition-Elomonation Reactions of β-Oxygenated Vinyl Sulphines

Giblin, Gerard M. P.,Simpkin, Nigel S.

, p. 207 - 208 (2007/10/02)

Stereoselective reaction of enol pivalate (3) with a variety of higher order organocuprate reagents gives vinyl sulphones in excellent yield.
