Check Digit Verification of cas no

The CAS Registry Mumber 19971-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,7 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19971-12:
(7*1)+(6*9)+(5*9)+(4*7)+(3*1)+(2*1)+(1*2)=141
141 % 10 = 1
So 19971-12-1 is a valid CAS Registry Number.

Facile synthesis of 3-formyl-2,2,5,5-tetramethyl-1-oxypyrroline

Stork, Sebastian W.,Makinen, Marvin W.

, p. 1309 - 1312 (1999)

The spin-label compound 3-formyl-2,2,5,5-tetramethyl-1-oxypyrroline was synthesized from inexpensive starting materials in a sequence of four experimentally undemanding, but high yield achieving transformations. The key step is reduction of an N-methoxy-N-methylcarboxamide to an aldehyde functionality.

Synthesis of Chiral Spin-Labeled Amino Acids

Vuong, Wayne,Mosquera-Guagua, Fabricio,Sanichar, Randy,McDonald, Tyler R.,Ernst, Oliver P.,Wang, Lei,Vederas, John C.

supporting information, p. 10149 - 10153 (2019/12/24)

Spin-labeled amino acids (SLAAs) are often used to determine intermolecular distances and conformations in proteins via double electron-electron resonance. Currently available SLAAs can be difficult to incorporate selectively and have little resemblance to natural side chains in proteins. Enantioselective synthesis of three spin-labeled l-amino acids is described, starting from readily available 2,2,6,6-tetramethyl-4-piperidinone. These SLAAs better replicate canonical residues in proteins and aim for biological incorporation via genetic incorporation or solid-phase peptide synthesis.
