213686-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213686-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,6,8 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213686-69:
(8*2)+(7*1)+(6*3)+(5*6)+(4*8)+(3*6)+(2*6)+(1*9)=142
142 % 10 = 2
So 213686-69-2 is a valid CAS Registry Number.

Stereocontrolled asymmetric synthesis of α-hydroxy-β-amino acids. A stereodivergent approach
Aoyagi,Jain,Williams
, p. 3472 - 3477 (2007/10/03)
The stereocontrolled asymmetric synthesis of α-hydroxy-β-amino acids has been investigated via the Lewis acid-promoted cyanation of (5R,6S)-2-acetoxy-4-(benzyloxycarbonyl)-5, 6-diphenyl-2,3,5,6-tetrahydro-4H-1,4-oxazines with trimethylsilyl cyanide. Base-
