29021-87-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29021-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,0,2 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29021-87:
(7*2)+(6*9)+(5*0)+(4*2)+(3*1)+(2*8)+(1*7)=102
102 % 10 = 2
So 29021-87-2 is a valid CAS Registry Number.

Cleavage of a carbon-carbon triple bond via gold-catalyzed cascade cyclization/oxidative cleavage reactions of (2)-enynols with molecular oxygen

Liu, Yuanhong,Song, Feijie,Guo, Shenghai

, p. 11332 - 11333 (2006)

A highly efficient carbon-carbon triple bond cleavage reaction of (Z)-enynols was developed, which offered a new route to highly substituted butenolides. The methodology is realized by a tandem reaction using a single gold(I) catalyst, which could catalyze different reactions of cyclization/oxidative cleavage in the same vessel. Copyright
