Check Digit Verification of cas no

The CAS Registry Mumber 1369903-38-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,9,9,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1369903-38:
(9*1)+(8*3)+(7*6)+(6*9)+(5*9)+(4*0)+(3*3)+(2*3)+(1*8)=197
197 % 10 = 7
So 1369903-38-7 is a valid CAS Registry Number.

Exploring α-chromonyl nitrones as 1,5-dipoles

Wittstein, Kathrin,García, Ana B.,Schürmann, Markus,Kumar, Kamal

supporting information; experimental part, p. 227 - 232 (2012/03/10)

N-Phenyl-C-chromonyl nitrones 1 and the allenoate zwitterion 2, generated by addition of phosphine to acetylenedicarboxylates, undergo a cascade reaction sequence involving an unprecedented [5+3] annulation followed by deoxygenative rearrangement leading to dihydropyridine-fused benzopyrones. Unusual electronic control by the N-substituents of 1 directs the annulation pathway, leading to two different ring-systems. Georg Thieme Verlag Stuttgart - New York.
