Check Digit Verification of cas no
The CAS Registry Mumber 944903-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,9,0 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 944903-27:
(8*9)+(7*4)+(6*4)+(5*9)+(4*0)+(3*3)+(2*2)+(1*7)=189
189 % 10 = 9
So 944903-27-9 is a valid CAS Registry Number.

Ruthenium-Catalyzed Propargylic Reduction of Propargylic Alcohols with Hantzsch Ester

Ruthenium-catalyzed propargylic reduction of propargylic alcohols bearing a terminal alkyne moiety is accomplished by using Hantzsch ester as a nucleophilic hydride source. A variety of secondary and tertiary propargylic alcohols are reduced to the corresponding propargylic reduced products such as 1-alkynes in excellent yields. Some mechanistic studies indicate that ruthenium-allenylidene complexes may work as key reactive intermediates.
