Check Digit Verification of cas no

The CAS Registry Mumber 203736-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,3 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 203736-22:
(8*2)+(7*0)+(6*3)+(5*7)+(4*3)+(3*6)+(2*2)+(1*2)=105
105 % 10 = 5
So 203736-22-5 is a valid CAS Registry Number.

Novel serine-based linker for the solid-phase synthesis of organic compounds

Chou, Yuo-Ling,Morrissey, Michael M.,Mohan, Raju

, p. 757 - 760 (2007/10/03)

A novel serine-derived linker has been developed that allows phenolic templates to be cleaved from the resin with fluoride ion. The linker is stable to acids such as TFA and bases such as pyrrolidine. The linker should provide utility in multi-step solid phase organic chemistry protocols where both acid and base chemistry is used.
