Check Digit Verification of cas no

The CAS Registry Mumber 160592-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,5,9 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 160592-66:
(8*1)+(7*6)+(6*0)+(5*5)+(4*9)+(3*2)+(2*6)+(1*6)=135
135 % 10 = 5
So 160592-66-5 is a valid CAS Registry Number.

Process for producing ortho-isopropylated phenol derivatives

-

, (2008/06/13)

This invention relates to the process for producing ortho-isopropylated phenol derivatives having following general formula (VIII). STR1 (in the above formula, R1 is a hydrogen or a low alkyl group of C1 -C4) A process for producing ortho-isopropylated phenol derivatives (VIII) of the present invention is characterized by obtaining position isomer desired by means of Claisen rearrangement of phenyl allyl ether without catalyst in atmosphere, and then obtaining only one isomer by oxidation and reduction of the above-obtained position isomer. According to the present invention, ortho-alkylated phenol derivatives (VIII) having high purity at low temperature and low pressure can be prepared without producing a by-product and requirement of the complicated separation procedure.
