27657-11-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27657-11-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,5 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27657-11:
(7*2)+(6*7)+(5*6)+(4*5)+(3*7)+(2*1)+(1*1)=130
130 % 10 = 0
So 27657-11-0 is a valid CAS Registry Number.

Method for NFSI-catalyzed synthesis of asymmetric disulphide derivatives

-

Paragraph 0018-0025; 0034, (2021/10/30)

The invention belongs to the field of fine chemical engineering, and relates to a method for NFSI-catalytically synthesizing an asymmetric disulphide derivative, which comprises the following steps: NFSI. The symmetric disulfide A and the symmetric disulf

Sulfur-Sulfur Bond Cleavage Processes. Selective Desulfurization of Trisulfides

Harpp, David N.,Smith, Roger A.

, p. 6045 - 6053 (2007/10/02)

The selectivity of sulfur removal in the desulfurization of trisulfides by tertiary phosphorus compounds has been investigated in detail.A mechanistic rationalization is proposed to account for central/terminal sulfur extrusion variation as a function of substrate structure and solvent polarity.
