Check Digit Verification of cas no
The CAS Registry Mumber 83481-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,8 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83481-29:
(7*8)+(6*3)+(5*4)+(4*8)+(3*1)+(2*2)+(1*9)=142
142 % 10 = 2
So 83481-29-2 is a valid CAS Registry Number.

Total Synthesis of Some Marasmane and Lactarane Sesquiterpenes
Thompson, Scott K.,Heathcock, Clayton H.
, p. 5979 - 5989 (2007/10/02)
A general and efficient synthetic route to the marasmane sesquiterpenes (+/-)-isovelleral (2) and (+/-)-stearoylvelutinal (1b) is described.Total syntheses of two other naturally occurring sesquiterpenes, deconjugated anhydrolactarorufin A (5) and lactarorufin A (6), were achieved using an acid-catalyzed ring expansion of lactone 25.All four syntheses are highly stereoselective and do not require the use of any protecting groups.Finally, the protic acid-catalyzed degradation of velutinal (1a) was investigated in an effort to chemically induce the biologically important conversion of velutinal (1a) to isovelleral (2).The experimental results thus obtained indicate that an enzymatic mechanism for the key transformation of velutinal (1a) into isovelleral (2) is more plausible than one that is acid-catalyzed.
