1228389-09-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228389-09-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,3,8 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228389-09:
(9*1)+(8*2)+(7*2)+(6*8)+(5*3)+(4*8)+(3*9)+(2*0)+(1*9)=170
170 % 10 = 0
So 1228389-09-0 is a valid CAS Registry Number.

Asymmetric synthesis of cyclic cis -β-Amino acid derivatives using sulfinimines and prochiral weinreb amide enolates
Davis, Franklin A.,Theddu, Naresh
, p. 3814 - 3820 (2010)
Figure presented Cyclic cis-β-amino Weinreb amides, valuable building blocks for the asymmetric synthesis of cyclic β-amino acids derivatives, are readily prepared via ring-closing metathesis of sulfinimine-derived N-sulfinyl β-amino diene Weinreb amides.
