2289-92-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2289-92-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,8 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2289-92:
(6*2)+(5*2)+(4*8)+(3*9)+(2*9)+(1*2)=101
101 % 10 = 1
So 2289-92-1 is a valid CAS Registry Number.

A facile method for the synthesis of 1,3-oxathiolan-2-ones by reaction of oxiranes, sulfur, and carbon monoxide

Nishiyama, Yutaka,Katahira, Chisato,Sonoda, Noboru

, p. 5803 - 5807 (2006)

A new method for the synthesis of 1,3-oxathiolan-2-ones has been developed. When oxiranes were allowed to react with sulfur in the presence of a catalytic amount of sodium hydride under pressurized carbon monoxide, the three-component coupling of oxiranes

Synthesis of cyclic monothiocarbonates via the coupling reaction of carbonyl sulfide (COS) with epoxides

Luo,Zhang,Darensbourg

, p. 188 - 192 (2016)

Two guanidine bases were used as organocatalysts for the synthesis of cyclic monothiocarbonates via the coupling reaction of carbonyl sulfide (COS) and epoxides. The systems proved to be efficient single-component, metal-free catalysts for the reaction of
