Check Digit Verification of cas no

The CAS Registry Mumber 473536-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,5,3 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 473536-83:
(8*4)+(7*7)+(6*3)+(5*5)+(4*3)+(3*6)+(2*8)+(1*3)=173
173 % 10 = 3
So 473536-83-3 is a valid CAS Registry Number.

1,2-Diaza-1,3-butadienes: A new approach to the synthesis of selenoheterocycles

Attanasi, Orazio A.,Filippone, Paolino,Perrulli, Francesca R.,Santeusanio, Stefania

, p. 2323 - 2330 (2002)

1,2-Diaza-1,3-butadienes react easily with selenoureas to produce 2-selenazolin-4-one derivatives and with selenobenzamide to afford 2-selenazoline derivatives, the stereochemistries of which were determined. Whereas 2-selenazoline derivatives of 4R*,5R* configuration undergo aromatization under basic conditions, 2-selenazolin-4-ones, under different reaction conditions, appear to be attractive entry compounds to conjugated azoalkenes, 5,5-disubstituted selenazolin-4-ones, and spiro-condensed heterocyclic systems including selenazolinone rings.
