51006-81-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51006-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,0,0 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51006-81:
(7*5)+(6*1)+(5*0)+(4*0)+(3*6)+(2*8)+(1*1)=76
76 % 10 = 6
So 51006-81-6 is a valid CAS Registry Number.

Isomerization of propargylic alcohols into α,β-unsaturated carbonyl compounds catalyzed by the sixteen-electron allyl-ruthenium(II) complex [Ru(η3-2-C3H4Me)(CO)(dppf)] [SbF 6]

Cadierno, Victorio,Garcia-Garrido, Sergio E.,Gimeno, Jose

, p. 101 - 110 (2007/10/03)

The 16-e- (η3-allyl)-ruthenium(II) complex [Ru(η3-2-C3H4Me)(CO)(dppf)][SbF 6] is an efficient catalyst for the regioselective isomerization of terminal propargylic alcohols HC≡CCR1R2(OH) into α,β-unsaturated aldehydes R1R2C=CHCHO or ketones R3R4C=C(R1)COMe (if R2 = CHR3R4) under mild conditions. This complex has been also used as catalyst for the preparation of conjugated 1,3-enynes via dehydration of propargylic alcohols.
