Check Digit Verification of cas no

The CAS Registry Mumber 628718-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,8,7,1 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 628718-91:
(8*6)+(7*2)+(6*8)+(5*7)+(4*1)+(3*8)+(2*9)+(1*1)=192
192 % 10 = 2
So 628718-91-2 is a valid CAS Registry Number.

Studies on isocyanides and related compounds: A facile synthesis of 1,6-dihydro-6-oxopyrazine-2-carboxylic acid derivatives via Ugi four-component condensation

Faggi, Cristina,Garcia-Valverde, Maria,Marcaccini, Stefano,Pepino, Roberto,Pozo, Ma. Cruz

, p. 1553 - 1558 (2007/10/03)

The Ugi four-component condensation (U-4CC) between arylglyoxals 7, amines 6, benzoylformic acid (4) and isocyanides 5 afforded the expected products 8 which were cyclized in a 5+1 fashion with ammonium acetate to give 1,N-disubstituted 4-aryl-1,6-dihydro-6-oxo-5-phenylpyrazine-2-carboxamides 9 in good yields. Evidence for the assigned structures 9 was provided by 13C NMR spectra and X-ray analysis of 9a.
