Check Digit Verification of cas no

The CAS Registry Mumber 92431-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,4,3 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92431-79:
(7*9)+(6*2)+(5*4)+(4*3)+(3*1)+(2*7)+(1*9)=133
133 % 10 = 3
So 92431-79-3 is a valid CAS Registry Number.

Ruthenium-Catalyzed Propargylic Reduction of Propargylic Alcohols with Hantzsch Ester

Ding, Haowei,Sakata, Ken,Kuriyama, Shogo,Nishibayashi, Yoshiaki

, p. 2130 - 2134 (2020)

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.
