99930-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99930-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,3 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99930-76:
(7*9)+(6*9)+(5*9)+(4*3)+(3*0)+(2*7)+(1*6)=194
194 % 10 = 4
So 99930-76-4 is a valid CAS Registry Number.

A NOVEL METHOD FOR THE PREPARATION OF SYMMETRICAL AND UNSYMMETRICAL ETHERS. TRITYL PERCHLORATE PROMOTED REDUCTION OF CARBONYL COMPOUNDS WITH TRIETHYLSILANE

Kato, Jun-ichi,Iwasawa, Nobuharu,Mukaiyama, Teruaki

, p. 743 - 746 (1985)

In the presence of a catalytic amount of trityl perchlorate, symmetrical ethers are prepared from aldehydes and triethylsilane, and unsymmetrical ethers are also obtained from carbonyl compounds, alkoxytrimethylsilanes and triethylsilane, in good yields, respectively.

Bismuth trichloride catalyzed efficient reductive etherification of carbonyl compounds with alcohols: A novel method for preparation of symmetrical and unsymmetrical ethers

Wada, Makoto,Nagayama, Sonoe,Mizutani, Kaori,Hiroi, Ryoichi,Miyoshi, Norikazu

, p. 248 - 249 (2007/10/03)

The reductive homocoupling of a carbonyl compound and heterocoupling of a carbonyl compound with a non-protected alcohol were both effected smoothly at room temperature with triethylsilane in the presence of a catalytic amount of bismuth trichloride to afford the corresponding ethers in good yields.
