Check Digit Verification of cas no

The CAS Registry Mumber 55377-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,7 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55377-22:
(7*5)+(6*5)+(5*3)+(4*7)+(3*7)+(2*2)+(1*2)=135
135 % 10 = 5
So 55377-22-5 is a valid CAS Registry Number.

Preparation of zinc organometallics derived from nucleosides and nucleic acid bases and Pd(0) catalyzed coupling with aryl iodides

Stevenson, Thomas M.,Prasad, A. S. Bhanu,Citineni, Janakiram Rao,Knochel, Paul

, p. 8375 - 8378 (1996)

5-Iodouracil and 6-iodopurine derivatives readily insert zinc dust (25°C or 70°C) in THF or DMAC affording zincated nucleic acid base derivatives which undergo efficient palladium catalyzed cross-coupling reactions with aryl iodides in good yields. This r

Paragraph 0044; 0045; 0046; 0047; 0048; 0049; 0050-0053, (2017/07/01)

The invention relates to a preparation method of 1,3-dimethyl-5-phenyluracil. The preparation method includes mixing phenylamine, water and a fluoboric acid water solution, dropwise adding a water solution of sodium nitrite with stirring for 1-2 hours at 0-5 DEG C and performing suction filtration so as to obtain phenyldiazonium tetrafluoroborate; at the room temperature, adding 1,3-dimethyluracil and a copper salt catalyst into a solvent with stirring and mixing, adding the phenyldiazonium tetrafluoroborate in batches, stirring to react for 8-12 hours after addition is finished, and conducting separation and purification so as to obtain the 1,3-dimethyl-5-phenyluracil. The preparation method has the advantages of simplicity in operation, short reaction route, less reaction time, high product yield and suitability for industrialized production.

Switching the regioselectivity of direct C-H arylation of 1,3-Dimethyluracil

Cernova, Miroslava,Pohl, Radek,Hocek, Michal

experimental part, p. 3698 - 3701 (2009/12/03)

An interesting dichotomy in the regioselectivity and mechanism of direct C-H arylation of 1,3-dimethyluracil was observed. Its Pd-catalyzed reactions with diverse aryl halides in the absence of Cui lead preferentially to 5-aryluracils, while reactions in
