Check Digit Verification of cas no
The CAS Registry Mumber 136476-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,7 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136476-04:
(8*1)+(7*3)+(6*6)+(5*4)+(4*7)+(3*6)+(2*0)+(1*4)=135
135 % 10 = 5
So 136476-04-5 is a valid CAS Registry Number.

Enantioselective Terpene Syntheses by Diels-Alder Reaction of 1-(1-Arylalkoxy)-2-methyl-1,3-butadiene with Isoprene
Zadel, Guido,Rieger, Rainer,Breitmaier, Eberhard
, p. 1343 - 1346 (2007/10/02)
The (R)- and (S)-1-(1-arylalkoxy)-2-methyl-1,3-butadienes 6 undergo cycloadditions with excess isoprene (7) under pressure to yield not only the expected (4S,6R)- and (4R,6S)-trans-carveol (8) with up to 96percent e.e. but also up to 40percent of (R)- and (S)-limonene (9) with up to 93percent e.e.Asymmetric induction is proposed to arise from a transition state involving definite ? stacking of one molecule of isoprenyl ether and two molecules of isoprene.Key Words: (4S,6R)-, (4R,6S)-trans-Carveol / (R)-, (S)-Limonene / Isoprene / Isoprenyl ether / Cycloaddition, diastereo-, enantioselective
