132903-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132903-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132903-72:
(8*1)+(7*3)+(6*2)+(5*9)+(4*0)+(3*3)+(2*7)+(1*2)=111
111 % 10 = 1
So 132903-72-1 is a valid CAS Registry Number.

Cyclic sulphamidates: New synthetic precursors for β-functionalised α-amino acids
Baldwin,Spivey,Schofield
, p. 881 - 884 (2007/12/18)
The nucleophilic ring opening of cyclic sulphamidates derived from (S)-serine by a variety of nucleophiles, was utilised in a novel approach to the synthesis of β-substituted alanines.
