Check Digit Verification of cas no

The CAS Registry Mumber 31151-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,5 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31151-37:
(7*3)+(6*1)+(5*1)+(4*5)+(3*1)+(2*3)+(1*7)=68
68 % 10 = 8
So 31151-37-8 is a valid CAS Registry Number.

Silazanes/catalytic bases: Mild, powerful and chemoselective agents for the preparation of enol silyl ethers from ketones and aldehydes

Tanabe, Yoo,Misaki, Tomonori,Kurihara, Minoru,Iida, Akira,Nishii, Yoshinori

, p. 1628 - 1629 (2007/10/03)

We have developed an efficient method for the preparation of enol silyl ethers using novel agents, silazanes together with NaH or DBU catalyst, wherein TMS and TBDMS groups were smoothly and chemoselectively introduced into ketones and aldehydes under mil

A CONVENIENT PREPARATION METHOD OF THE VINYLIC HALIDE ISOMER OF CHLOROTRIMETHYLSILYL ENOL ETHERS

Poirier, Jean-Marie,Hennequin, Laurent

, p. 217 - 224 (2007/10/02)

Reaction of trimethylsilyliodide (generated in situ from trimethylsilylchloride and sodium iodide) in the presence of triethylamine in acetonitrile with α-chloroketones yields the vinylic halide isomer of chlorotrimethylsilyl enol ethers.
