Check Digit Verification of cas no

The CAS Registry Mumber 1292254-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,2,5 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1292254-18:
(9*1)+(8*2)+(7*9)+(6*2)+(5*2)+(4*5)+(3*4)+(2*1)+(1*8)=152
152 % 10 = 2
So 1292254-18-2 is a valid CAS Registry Number.

METHOD FOR PRODUCING M-SUBSTITUTED PHENYLALKANOLS BY MEANS OF ISOMERIZATION

-

Page/Page column 5, (2012/08/28)

The invention relates to a process for the preparation of m-substituted phenylalkanols of the formula (I) in which R1 is C1-C5-alkyl and R2, R3, R4 and R5, independently of one another, are hydrogen or methyl, wherein a p-substituted phenylalkanol of the formula (II) in which R1, R2, R3, R4 and R5 having the meanings given under formula (I), is isomerized in the presence of a Friedel-Crafts catalyst to give an m-substituted phenylalkanol of the formula (I). From the m-substituted phenylalkanols of the formula (I) it is possible to form, by oxidation or dehydrogenation, as products of value, the corresponding aldehydes, which are known as fragrances and aroma chemicals.
