Check Digit Verification of cas no

The CAS Registry Mumber 211053-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,0,5 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 211053-96:
(8*2)+(7*1)+(6*1)+(5*0)+(4*5)+(3*3)+(2*9)+(1*6)=82
82 % 10 = 2
So 211053-96-2 is a valid CAS Registry Number.

PhFl acetic acid: A new linker for solid phase organic synthesis

Bleicher, Konrad H.,Wareing, James R.

, p. 4591 - 4594 (1998)

A 9-phenylfluoren-9-yl based linker for the immobilization of nitrogen and oxygen nucleophiles is described. Improved acid stability compared to the common trityl linker is demonstrated by a quantitative method for analysis of loading. This new linker is used for the synthesis of a peptide alcohol in the 'inverse' direction via reduction of the corresponding N linked peptide methyl ester. Several other nucleophiles are immobilized and further modified. TFA treatment releases the corresponding products in high purity.
