143870-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143870-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143870-63:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*0)+(2*6)+(1*3)=137
137 % 10 = 7
So 143870-63-7 is a valid CAS Registry Number.

Stereoselective synthesis of β-hydroxy-α-amino acids from chiral cyanohydrins
Zandbergen,Brussee,Van Der Gen,Kruse
, p. 769 - 774 (2007/10/02)
An efficient one-pot reduction-transimination-hydrocyanation synthesis of β-hydroxy-α-cyanoamines 3 from optically active O-protected mandelonitrile (1) is described. These β-hydroxy-α-cyanoamines were easily converted into optically active (2S,3R) β-hydr
