126861-75-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126861-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,6 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126861-75:
(8*1)+(7*2)+(6*6)+(5*8)+(4*6)+(3*1)+(2*7)+(1*5)=144
144 % 10 = 4
So 126861-75-4 is a valid CAS Registry Number.

Continuous Pd-Catalyzed Carbonylative Cyclization Using Iron Pentacarbonyl as a CO Source

Lopatka, Pavol,Markovi?, Martin,Koó?, Peter,Ley, Steven V.,Gracza, Tibor

, p. 14394 - 14406 (2019/11/11)

This work discloses a continuous flow carbonylation reaction using iron pentacarbonyl as source of CO. The described transformation using this surrogate was designed for use in commonly accessible flow equipment. Optimized conditions were applied to a sca

ELECTROPHILIC OLEFIN HETEROCYCLIZATION IN ORGANIC SYNTHESIS. STEREOSELECTIVE INTRAMOLECULAR AMIDOMERCURATION OF γ-HYDROXY-δ,ε-UNSATURATED URETHANES
