838853-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 838853-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,8,8,5 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 838853-45:
(8*8)+(7*3)+(6*8)+(5*8)+(4*5)+(3*3)+(2*4)+(1*5)=215
215 % 10 = 5
So 838853-45-5 is a valid CAS Registry Number.

Organolithium-mediated diversification of peptide thiazoles
Deng, Shaojiang,Taunton, Jack
, p. 299 - 301 (2007/10/03)
(Chemical Equation Presented) We report a one-step, racemization-free method for the diversification of peptide thiazoles via direct lithiation of the thiazole ring. The method is compatible with N-Boc, N-trityl, carboxylic ester, and carboxamide protecti
