Check Digit Verification of cas no

The CAS Registry Mumber 1193402-39-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,4,0 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1193402-39:
(9*1)+(8*1)+(7*9)+(6*3)+(5*4)+(4*0)+(3*2)+(2*3)+(1*9)=139
139 % 10 = 9
So 1193402-39-9 is a valid CAS Registry Number.

Synthesis of substituted fused pyridines, pyrazines and pyrimidines by sequential Ugi/inverse electron demand Diels-Alder transformations

Akritopoulou-Zanze, Irini,Wang, Ying,Zhao, Hongyu,Djuric, Stevan W.

body text, p. 5773 - 5776 (2009/12/26)

The synthesis of all four regioisomers of fused pyrrolidino-pyridines in a one-pot two-step sequential Ugi-inverse electron demand Diels-Alder reaction is described. Fused pyrrolidino-pyrazines, pyrrolidino-pyrimidines and azepinone pyridines can also be obtained in consecutive synthetic sequences.
