25180-82-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25180-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,8 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25180-82:
(7*2)+(6*5)+(5*1)+(4*8)+(3*0)+(2*8)+(1*2)=99
99 % 10 = 9
So 25180-82-9 is a valid CAS Registry Number.

A highly efficient one-pot method for the synthesis of thioureas and 2-imino-4-thiazolidinones under microwave conditions

Chau, Chi-Min,Chuan, Tzu-Jung,Liu, Kuan-Miao

, p. 1276 - 1282 (2014/01/06)

A one-pot synthesis of symmetrical and unsymmetrical substituted thioureas and 2-imino-4-thiazolidinones from simple starting materials under microwave irradiation and solventless conditions without base additives is presented. Various di- and trisubstituted thioureas are obtained in good yields in a few minutes. The sequential, three-component, one-pot synthesis of 2-imino-4-thiazolidinone derivatives is also studied, with satisfactory results obtained.

Self-indicating amine scavenger resins

Cho, Jin Ku,White, Peter D.,Klute, Wolfgang,Dean, Tony W.,Bradley, Mark

, p. 502 - 503 (2007/10/03)

Self-indicating methylisocyanate resin, which functions as both a scavenger and an indicator for amines, was used for in-situ reaction monitoring and purification of a urea based library.
