Calculate Digit Verification of CAS Registry Number 129948-31:
(8*1)+(7*2)+(6*9)+(5*9)+(4*4)+(3*8)+(2*3)+(1*1)=168
168 % 10 = 8
So 129948-31-8 is a valid CAS Registry Number.

Synthesis of Acylated Thioureylenedisaccharides

Avalos, Martin,Babiano, Reyes,Cintas, Pedro,Jimenez, Jose L.,Palacios, Juan C.,Fuentes, Jose

, p. 495 - 501 (2007/10/02)

Thioureylenedisaccharides have been prepared from sugar isothiocyanates and aminosugars.Thus, a thiourea bridge connects the (C-1)-(C-2) or (C-2)-(C-2) positions of some pentose, hexose, and heptose frameworks with different anomeric patterns in compounds (16)-(28).With this aim, several C-2-functionalised derivatives of compound (7) have been synthesized.A (Z,Z)-conformation is proposed for thioureylenedisaccharides in solution.
