129090-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129090-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,9 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129090-81:
(8*1)+(7*2)+(6*9)+(5*0)+(4*9)+(3*0)+(2*8)+(1*1)=129
129 % 10 = 9
So 129090-81-9 is a valid CAS Registry Number.

Synthesis of stereospecifically labeled 3,6-dideoxyhexoses.
Russell,Weigel,Han,Liu
, p. 95 - 114 (2007/10/02)
Preparations of ascarylose (3,6-dideoxy-L-arabino-hexose), abequose (3,6-dideoxy-D-xylo-hexose), and paratose (3,6-dideoxy-D-ribo-hexose) with stereospecific deuterium labeling at C-3 are discussed. The methods used to synthesize these sugars, such as the
