Check Digit Verification of cas no

The CAS Registry Mumber 637009-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,0 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 637009-13:
(8*6)+(7*3)+(6*7)+(5*0)+(4*0)+(3*9)+(2*1)+(1*3)=143
143 % 10 = 3
So 637009-13-3 is a valid CAS Registry Number.

Syntheses of showdomycin and its anomer using N-(triisopropylsilyl)pyrrole as a synthetic equivalent for the maleimide C3-anion

Hungerford, Natasha L.,Armitt, David J.,Banwell, Martin G.

, p. 1837 - 1843 (2007/10/03)

Showdomycin (1) and its anomer (2) have been prepared in four steps from readily available trichloroacetimidate 9. The key step involves reaction of the last compound with the title pyrrole 3 so as to form a chromatographically separable mixture of the pyrrole C-glycosides 10 and 11. These pyrroles are desilylated then oxidized to the corresponding maleimides using PCC.
