Check Digit Verification of cas no

The CAS Registry Mumber 99141-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,4 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99141-45:
(7*9)+(6*9)+(5*1)+(4*4)+(3*1)+(2*4)+(1*5)=154
154 % 10 = 4
So 99141-45-4 is a valid CAS Registry Number.

, p. 569 - 574 (2007/10/02)

Raney nickel hydrogenation of Z-3-aryl-5-(ethoxycarbonyl)methylene-5,6-dihydro-4H-1,2,4-oxadiazine (1a-c) affords 2-aryl-6-hydroxymethyl-4-pyrimidinone (2) and ethyl (2-aryl-4-oxazolyl)acetate (3).A similar hydrogenation of Z-5-(arylcarbamoyl)methylene-5,

RING-TRANSFORMATION OF 1,2,4-OXADIAZINE DERIVATIVES INTO 4-HYDROXYPYRIMIDINE DERIVATIVES: CATALYTIC HYDROGENATION OF 3-ARYL-5-ETHOXYCARBONYLMETHYLENE-5,6-DIHYDRO-4H-1,2,4-OXADIAZINE DERIVATIVES

Tabei, Katsumi,Kawashima, Etsuko,Takada, Toyozo,Kato, Tetsuzo

, p. 2061 - 2066 (2007/10/02)

Catalytic hydrogenation of 3-aryl-5-ethoxycarbonylmethylene-5,6-dihydro-4H-1,2,4-oxadiazine derivatives (1) is described.The method leads to new synthesis of 2-aryl-4-hydroxypyrimidine derivatives (3) involving cyclization of ethyl 3-benzimidoylimino-4-hydroxybutanoate derivatives (2) by the elimination of ethanol.Nickel catalyzed hydrogenation of 1 gave ethyl 2-aryl-4-oxazoylacetate (4) as a by-product besides product 3.
