143245-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143245-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,4 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143245-70:
(8*1)+(7*4)+(6*3)+(5*2)+(4*4)+(3*5)+(2*7)+(1*0)=109
109 % 10 = 9
So 143245-70-9 is a valid CAS Registry Number.

The synthesis of chiral decalones, (-)-1,1,4a-trimethyl-2-decalol and (+)-geosmin from S-(+)-carvone (part 3)

Swarts, Henk J.,Haaksman, Anja A.,Jansen, Ben J. M.,De Groot, Aede

, p. 5497 - 5508 (1992)

The cholesterol biosynthesis inhibitor (-),1,1,4a-trimethyl-2-decalol (4), the chiral decalones 6 and 7, and (+)-geosmin (9 were synthesized from S-(+)-carvone. Annelation of S-(-)-dihydrocarvone followed by methylation gave compound 8 which was used as a
