Check Digit Verification of cas no

The CAS Registry Mumber 222713-08-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,7,1 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 222713-08:
(8*2)+(7*2)+(6*2)+(5*7)+(4*1)+(3*3)+(2*0)+(1*8)=98
98 % 10 = 8
So 222713-08-8 is a valid CAS Registry Number.

Thalidomide metabolites and analogues. 3. Synthesis and antiangiogenic activity of the teratogenic and TNFα-modulatory thalidomide analogue 2-(2,6-dioxopiperidine-3-yl)phthalimidine

Luzzio, Frederick A.,Mayorov, Alexander V.,Ng, Sylvia S. W.,Kruger, Erwin A.,Figg, William D.

, p. 3793 - 3799 (2007/10/03)

Versatile synthesis of the teratogenic, TNFα-modulatory, and antiangiogenic thalidomide analogue 2-(2,6-dioxopiperidine-3-yl)phthalimidine (1) and its direct antiangiogenic properties are described. With thalidomide or thalidomide derivatives as precursors, the synthesis involved either carbonyl reduction/thiation-desulfurization or carbonyl reduction/acyliminium ion reduction protocols. Compared to earlier studies with thalidomide, which was only active with microsomal treatment, 1 exhibited marginal inhibitory activity in the rat aortic ring assay, thereby demonstrating the requirement for metabolic activation.
