176967-11-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176967-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,9,6 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 176967-11:
(8*1)+(7*7)+(6*6)+(5*9)+(4*6)+(3*7)+(2*1)+(1*1)=186
186 % 10 = 6
So 176967-11-6 is a valid CAS Registry Number.

Conformationally restricted analogues of tryptophan: Synthesis of chiral 3-amino-4-indolyl-2-piperidones

Rodriguez, Ricardo,Vinets, Imma,Diez, Anna,Rubiralta, Mario,Giralt, Ernest

, p. 3029 - 3059 (1996)

The {Trp-phenylglycinol} pseudodipeptide (αR,3R*,4R*)-N-(2-acetoxy-1-phenylethyl)-3-amino-4-indolyl-2-piperi done 33 has been synthesized by condensation of the 3-amino-substituted anhydride 30 with (R)-(-)-phenylglycinol followed by reduction of the resulting imide.
