Check Digit Verification of cas no

The CAS Registry Mumber 855334-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,3,3 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 855334-35:
(8*8)+(7*5)+(6*5)+(5*3)+(4*3)+(3*4)+(2*3)+(1*5)=179
179 % 10 = 9
So 855334-35-9 is a valid CAS Registry Number.

Fluorous mixture synthesis of fused-tricyclic hydantoins. Use of a redundant tagging strategy on fluorinated substrates

Manku, Sukhdev,Curran, Dennis P.

, p. 4470 - 4473 (2005)

Simple HPLC experiments were used to identify a redundant tagging scheme wherein six different amino acids were tagged with only four fluorous tags. The tagged amino acids were converted to regiosiomeric mixtures of tricyclic hydantoins. Despite the lack of selectivity, the mixtures were demixed and detagged to give 11 individual pure products in just 25 steps.
