Check Digit Verification of cas no

The CAS Registry Mumber 119372-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,7 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119372-71:
(8*1)+(7*1)+(6*9)+(5*3)+(4*7)+(3*2)+(2*7)+(1*1)=133
133 % 10 = 3
So 119372-71-3 is a valid CAS Registry Number.

Difluorinated Danishefsky's Diene: A versatile C4 building block for the fluorinated six-membered rings

Amii, Hideki,Kobayashi, Takeshi,Terasawa, Hiroshi,Uneyama, Kenji

, p. 3103 - 3105 (2007/10/03)

(equation presented) A Mg(0)/Me3SiCl system was found to be affective for the preparation of difluoro Danishefsky's dienes 2, which involves selective C-F bond cleavage of trifluoromethyl ketones 3. Subsequent hetero Diels-Alder reactions of 2 with aldehydes and imines gave a variety of fluorinated six-membered heterocycles.

FLUORINE-CONTAINING ORGANOZINC REAGENTS. IV. REFORMATSKII-TYPE REACTIONS OF CHLORODIFLUOROACETIC ACID DERIVATIVES

Lang, Robert W.,Schaub, Bruno

, p. 2943 - 2946 (2007/10/02)

Chlorodifluoroacetic acid has shown to be a promising starting material for Reformatskii-type syntheses of fluorine-containing molecules and thus, it offers an attractive extension to what is known from rather expensive bromodifluoroacetic acid.
