139172-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139172-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,7 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139172-76:
(8*1)+(7*3)+(6*9)+(5*1)+(4*7)+(3*2)+(2*7)+(1*6)=142
142 % 10 = 2
So 139172-76-2 is a valid CAS Registry Number.

Yokoyama,Sujino,Irie,Togo
, p. 7269 - 7272 (2007/10/02)
The thermal reaction of sugar lactoxime O-vinyl ethers gave the corresponding 1,3-oxazoles bearing sugar moiety (ribose, glucose, mannose, and maltose) via a novel rearrangement. The reaction mechanism was briefly discussed.
