34070-22-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34070-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,7 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34070-22:
(7*3)+(6*4)+(5*0)+(4*7)+(3*0)+(2*2)+(1*2)=79
79 % 10 = 9
So 34070-22-9 is a valid CAS Registry Number.

Ruthenium-catalyzed S-propargylation of thiols enables the rapid synthesis of propargylic sulfides

Kondo, Teruyuki,Kanda, Yusuke,Baba, Atsushi,Fukuda, Kenji,Nakamura, Ayako,Wada, Kenji,Morisaki, Yasuhiro,Mitsudo, Take-aki

, p. 12960 - 12961 (2002)

A new and highly efficient catalytic system based on CpRuClL2 is proposed for the S-propargylation of thiols by propargylic carbonates under neutral conditions, in which specific requirements inherent to the different reactivities of aliphatic and aromatic thiols are achieved by tuning both the nature of the ancillary ligand L and the experimental conditions.
