Check Digit Verification of cas no

The CAS Registry Mumber 95495-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,4,9 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 95495-81:
(7*9)+(6*5)+(5*4)+(4*9)+(3*5)+(2*8)+(1*1)=181
181 % 10 = 1
So 95495-81-1 is a valid CAS Registry Number.

SYNTHETIC STUDIES ON THE OCHTODANE TYPE TERPENES I. STEREOSELECTIVE CONSTRUCTION OF THE OCHTODANE SKELETON FROM MYRCENE.

Masaki,Hashimoto,Sakuma,Kaji

, p. 3466 - 3475 (2007/10/02)

The ochtodane skeleton, the Carbon framework of 1,1-dimethyl-3-ethylcyclohexane (1) was constructed highly stereoselectively by the acid-catalyzed (SnCl//4 or CF//3CO//2H) cyclization of the terminally functionalized myrcene derivatives, the benzenesulfenyl chloride adduct (7), the terminal beta -hydroxy sulfide (8) derived from 7, and myrcene 6,7-epoxide (10). The stereoselectivity of the 3-exo-double bond in 1 formed concomitantly in the cyclization reaction was found to depend remarkably upon the reaction temperture and the 85-94% of E-stereoselectivity was attained at minus 78 degree C. By the method, the ochtodane derivatives with the sulfur- or oxygen-functional groups on the C(6)-position were obtained.
