Check Digit Verification of cas no

The CAS Registry Mumber 478491-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,4,9 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 478491-35:
(8*4)+(7*7)+(6*8)+(5*4)+(4*9)+(3*1)+(2*3)+(1*5)=199
199 % 10 = 9
So 478491-35-9 is a valid CAS Registry Number.

Synthesis of a novel, recyclable, solid-phase acylating reagent.

Nicewonger, Robert B,Ditto, Lori,Kerr, Doug,Varady, Laszlo

, p. 1799 - 1802 (2002)

In this paper, we describe the synthesis of N-(6-cyano-1,3-dimethyl-2,4-dioxo-5-substituted-1,3-dihydropyridino[2,3-d] pyrimidin-7-yl)imides 1. We will show the synthesis of 1 using both conventional heating and microwave techniques. In addition, the imide was attached to polystyrene and this immobilized imide was equally as effective at acylating various primary and secondary amines as its solution-phase counterpart.
