Check Digit Verification of cas no

The CAS Registry Mumber 214554-37-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,5,5 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 214554-37:
(8*2)+(7*1)+(6*4)+(5*5)+(4*5)+(3*4)+(2*3)+(1*7)=117
117 % 10 = 7
So 214554-37-7 is a valid CAS Registry Number.

Fluorinated linkers for monitoring solid-phase synthesis using gel- phase 19F NMR spectroscopy

Svensson, Anette,Bergquist, Karl-Erik,Fex, Tomas,Kihlberg, Jan

, p. 7193 - 7196 (2007/10/03)

Three fluorinated linkers which are analogues of linkers commonly used in solid-phase peptide synthesis have been prepared. Using 19F NMR spectroscopy, the fluorine atom of the linker allowed monitoring of several transformations in the solid-phase synthesis of a peptoid having a coumarin moiety. Especially, attachment of the linker to the solid phase, coupling of the first building block to the linker and cleavage of the product were efficiently monitored and optimised.
