Check Digit Verification of cas no

The CAS Registry Mumber 119839-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,3 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119839-17:
(8*1)+(7*1)+(6*9)+(5*8)+(4*3)+(3*9)+(2*1)+(1*7)=157
157 % 10 = 7
So 119839-17-7 is a valid CAS Registry Number.

Optically active aromatic carboxylic acid derivatives and process for producing the same

-

, (2008/06/13)

Disclosed are optically active aromatic carboxylic acid derivatives represented by the formula (I): STR1 (wherein R2 represents an alkoxyalkyl group having 1 to 20 carbon atoms or an alkyl group having 1 to 20 carbon atoms, which alkyl group may be substituted with a halogen atom; represents a number of 1 or 2; m represents a number of 0 or 1; and * indicates asymmetric carbon atom) and a process for producing such derivatives through the following reaction steps: STR2 The optically active aromatic carboxylic acid derivatives represented by the above-described formula (I) are useful as a liquid crystal material and can be also utilized as an intermeidate for the preparation of pharmaceuticals, agricultural chemicals and the like.
