Check Digit Verification of cas no

The CAS Registry Mumber 55561-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,6 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55561-42:
(7*5)+(6*5)+(5*5)+(4*6)+(3*1)+(2*4)+(1*2)=127
127 % 10 = 7
So 55561-42-7 is a valid CAS Registry Number.

AlCl3-N,N-DIMETHYLANILINE: A NEW BENZYL AND ALLYL ETHER CLEAVAGE REAGENT.

Akiyama, Takahiko,Hirofuji, Hajimu,Ozaki, Shoichiro

, p. 1321 - 1324 (1991)

Benzyl and allylethers have been cleaved readily on treatment with AlCl3 and N,N-dimethylaniline to give parent alcohols in high yields.Comparisons of N,N-dimethylaniline and anisole are also described.

supporting information; experimental part, p. 2261 - 2264 (2010/07/10)

A chemometric process consisting in measuring the reactivity of a set of substrates under standardized and complementary reaction conditions was run to evaluate the possibility of building a coherent database that would give a general overview of the sele

Access to new steroids via a (1,2) Wittig rearrangement

Stephan, Elie,Dousset, Magali,Foy, Nicolas,Jaouen, Gerard

, p. 506 - 507 (2007/10/03)

Novel steroids are obtained by reaction of 9, 11-dehydro- dibenzylestradiol and dibenzylestradiol with phenyllithium in THF at room temperature.

AlCl3-N,N-Dimethylaniline: A Novel Benzyl and Allyl Ether Cleavage Reagent

Akiyama, Takahiko,Hirofuji, Hajimu,Ozaki, Shoichiro

, p. 1932 - 1938 (2007/10/02)

A combination system of AlCl3-N,N-dimethylaniline was found to cleave benzyl ethers readily to give parent alcohols in excellent yields.The system also cleaved allyl as well as methyl ethers.Numerous functional groups such as benzoyloxy, phenylthio, and olefinic double bond were not affected.Comparison of AlCl3-N,N-dimethylaniline and AlCl3-anisole were described.
