Check Digit Verification of cas no

The CAS Registry Mumber 95778-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,7,7 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 95778-56:
(7*9)+(6*5)+(5*7)+(4*7)+(3*8)+(2*5)+(1*6)=196
196 % 10 = 6
So 95778-56-6 is a valid CAS Registry Number.

The Synthesis of 9-Substituted p-Mentha-1,8(10)-diene Derivatives

Suemune, Hiroshi,Iwasaki, Genji,Ueno, Kohshi,Sakai, Kiyoshi

, p. 4632 - 4636 (2007/10/02)

The chemical conversion of (+)-limonene (1) and (-)-perillyl alcohol (10) into 9-substituted p-mentha-1,8(10)-diene derivatives is described.The lithiated species of 1 and 10 were easily obtained in good yields, by using sec-butyl lithium in N,N,N',N'-tetramethylethylenediamine.The reaction of the lithiated species (A and B) with various electrophiles was completed within 1-2h to give 9-substituted p-mentha-1,8(10)-diene derivatives.The stereochemistry of the chiral center of the starting material was retained in the products. 9-Hydroxy-p-mentha-1,8(10)-diene(8) was also obtained by another short sequence of steps.Oxidation of the phenylthio derivative (7) gave the sulfoxide (9).Treatment of 9 with trimethyl phosphite afforded 8.Keywords - synthesis; lithiation; limonene; perillyl alcohol; electrophile
