71127-55-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71127-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,2 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71127-55:
(7*7)+(6*1)+(5*1)+(4*2)+(3*7)+(2*5)+(1*5)=104
104 % 10 = 4
So 71127-55-4 is a valid CAS Registry Number.

Ruthenium-Catalyzed Cyclocarbonylation of Allenyl Alcohols and Amines: Selective Synthesis of Lactones and Lactams

Yoneda, Eiji,Zhang, Shi-Wei,Zhou, Da-Yang,Onitsuka, Kiyotaka,Takahashi, Shigetoshi

, p. 8571 - 8576 (2003)

Allenyl alcohols such as 4-hydroxybuta-1,2-dienes and 5-hydroxypenta-1,2-dienes having a variety of substituents undergo cyclocarbonylation in the presence of a ruthenium catalyst under mild conditions selectively to give five- and six-membered lactones in a high yield with 100% atom economy. 5-Aminopenta-1,2-dines are also cyclocarbonylated to give γ-lactams. A possible carbonylation mechanism involving a ruthenium cluster intermediate is proposed on the basis of experimental results.
