Check Digit Verification of cas no

The CAS Registry Mumber 1284399-87-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,3,9 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1284399-87:
(9*1)+(8*2)+(7*8)+(6*4)+(5*3)+(4*9)+(3*9)+(2*8)+(1*7)=206
206 % 10 = 6
So 1284399-87-6 is a valid CAS Registry Number.

Synthesis of sterically hindered N-acylated amino acids from N-carboxyanhydrides

Schaefer, Gabriel,Bode, Jeffrey W.

supporting information, p. 1526 - 1529 (2014/04/03)

Sterically hindered N-acyl, gem-disubstituted amino acids are easily prepared via the addition of organometallic reagents to N-carboxyanhydrides (NCA). The process tolerates a wide variety of functional groups and allows the synthesis of amide products not readily accessible by traditional acylation chemistry. The existence of an isocyanate intermediate was established by in situ IR spectroscopy.
