Check Digit Verification of cas no

The CAS Registry Mumber 469876-36-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,9,8,7 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 469876-36:
(8*4)+(7*6)+(6*9)+(5*8)+(4*7)+(3*6)+(2*3)+(1*6)=226
226 % 10 = 6
So 469876-36-6 is a valid CAS Registry Number.

Efficient 2-amino-2-thiazolin-4-ones or 2-iminothiazolidin-4-ones formation from thioureas and maleimides under solvent-free conditions

Shimo, Tetsuro,Matsuda, Yuki,Iwanaga, Tetsuo,Shinmyozu, Teruo,Somekawa, Kenichi

, p. 1053 - 1058 (2008/02/08)

A facile method for the construction of 2-thiazolin-4-one or thiazolidin-4-one structure is described. Condensation reactions of thiourea (1a) and maleimides (2) under solvent-free conditions gave 2-amino-2-thiazolin-4-ones (3) via Michael-type reaction, while similar reactions of N-substituted thioureas (1b-d) with 2 afforded 2-iminothiazolidin-4-ones (4). Since the solvent-free reactions of 1 with 2a afforded 3 in good yields, the synthetic method was found to be effective from the viewpoint of green chemistry.
