Check Digit Verification of cas no

The CAS Registry Mumber 28221-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,2 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28221-34:
(7*2)+(6*8)+(5*2)+(4*2)+(3*1)+(2*3)+(1*4)=93
93 % 10 = 3
So 28221-34-3 is a valid CAS Registry Number.

Mechanistic Studies on Thiazolidine Formation in Aldehyde/Cysteamine Model Systems

Huang, Tzou-Chi,Huang, Lee-Zen,Ho, Chi-Tang

, p. 224 - 227 (2007/10/03)

A mechanism was proposed to elucidate the formation of a thiazolidine in aldehyde/cysteamine model systems. Buffer dramatically promotes thiazolidine formation from formaldehyde and cysteamine. Phosphate tends to stabilize the primary carbocation formed, and this may lead to completion of the cyclization by attack of the amino nitrogen on the activated carbon. Protic solvent, by removing the water molecule, further enhances thiazolidine formation. Redox reaction catalyzed by phosphate ions results in the conversion of thiazolidine to the corresponding thiazoline through hydride transfer.
