90503-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90503-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,0 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90503-12:
(7*9)+(6*0)+(5*5)+(4*0)+(3*3)+(2*1)+(1*2)=101
101 % 10 = 1
So 90503-12-1 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
