Check Digit Verification of cas no

The CAS Registry Mumber 287919-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,9,1 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 287919-83:
(8*2)+(7*8)+(6*7)+(5*9)+(4*1)+(3*9)+(2*8)+(1*3)=209
209 % 10 = 9
So 287919-83-9 is a valid CAS Registry Number.

Convenient synthesis of 2,9-disubstituted guanines mediated by solid- supported reagents

McComas, Warren,Chen, Li,Kim, Kyungjin

, p. 3573 - 3576 (2000)

A novel application has been developed to separate regioisomers chemoselectively using a solid-supported reagent. An N7/N9 purine regioisomer mixture was purified using aluminum oxide/H+ to provide the N9 isomer selectively as a parallel or high-throughput format (chemoselective high- throughput purification). 2,9-Disubstituted guanines were conveniently prepared by this new method in conjunction with solid-supported reagents.
