862972-77-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862972-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,9,7 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 862972-77:
(8*8)+(7*6)+(6*2)+(5*9)+(4*7)+(3*2)+(2*7)+(1*7)=218
218 % 10 = 8
So 862972-77-8 is a valid CAS Registry Number.

Asymmetric Synthesis of Carbacyclin Precursors by Pauson-Khand Cyclization
Mulzer, Johann,Graske, Klaus-Dieter,Kirste, Burkhard
, p. 891 - 898 (2007/10/02)
The carbacyclin precursors 11, 17, 18 have been prepared from the en-ynes 10, 15, 16 by cobalt-mediated cyclization (Pauson-Khand reaction) with varying degrees of diastereoselectivity.
