Check Digit Verification of cas no
The CAS Registry Mumber 3017-68-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3017-68:
(6*3)+(5*0)+(4*1)+(3*7)+(2*6)+(1*8)=63
63 % 10 = 3
So 3017-68-3 is a valid CAS Registry Number.

On the basis of our observation that (E)-1-bromo-1-alkenes undergo preferentially stereospecific Pd-catalyzed cross-couplings with a variety of organometallics, in the presence of the corresponding (Z)-stereoisomers, efficient and convenient diastereoselective procedures have been developed to prepare nearly stereoisomerically pure (E)-1-trimethylsilyl-2-alkenes (4), (E)-1-trimethylsilyl-1-alken-3-ynes (5), (1E,5E)-1-trimethylsilyl-1,5-alkadien-3-ynes (6), and (1E,3E)-1-trimethylsilyl-1,3-alkadienes (8) from stereoisomeric mixtures of alkenyl bromides.Compounds 5 have been stereoselectively converted into (1E,3Z)-1-trimethylsilyl-1,3-dienes (7) by selective hydrometallations, followed by hydrolysis.Some synthetic applications of compounds 5-8 have been also examined.
