Check Digit Verification of cas no

The CAS Registry Mumber 852178-76-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,1,7 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 852178-76:
(8*8)+(7*5)+(6*2)+(5*1)+(4*7)+(3*8)+(2*7)+(1*6)=188
188 % 10 = 8
So 852178-76-8 is a valid CAS Registry Number.

An acid-stable tert-butyldiarylsilyl (TBDAS) linker for solid-phase organic synthesis

DiBlasi, Christine M.,Macks, Daniel E.,Tan, Derek S.

, p. 1777 - 1780 (2005)

(Chemical Equation Presented) A new, robust tert-butyldiarylsilyl (TBDAS) linker has been developed for solid-phase organic synthesis. This linker is stable to both protic and Lewis acidic reaction conditions, overcoming a significant limitation of previously reported silyl linkers. Solid-phase acetal deprotection, olefination, asymmetric allylation, and silyl protecting group deblocking reactions have been demonstrated with TBDAS-linked substrates.
