Check Digit Verification of cas no

The CAS Registry Mumber 211504-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,5,0 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 211504-71:
(8*2)+(7*1)+(6*1)+(5*5)+(4*0)+(3*4)+(2*7)+(1*1)=81
81 % 10 = 1
So 211504-71-1 is a valid CAS Registry Number.

Towards polyketide libraries - II: Synthesis of chiral aracemic DI- and triketides on a solid support

Reggelin, Michael,Brenig, Volker,Welcker, Reinhard

, p. 4801 - 4804 (1998)

A new fluoride ion cleavable linker serves as starter unit for iterative asymmetric aldol reactions on a solid support. The synthetic protocol relies on the boron enolate chemistry of D. A. Evans and a cyclic reestablishment of key functionalities. It entails the opportunity for the generation of di- and triketide libraries.
