Check Digit Verification of cas no

The CAS Registry Mumber 700358-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,0,3,5 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 700358-67:
(8*7)+(7*0)+(6*0)+(5*3)+(4*5)+(3*8)+(2*6)+(1*7)=134
134 % 10 = 4
So 700358-67-4 is a valid CAS Registry Number.

The first case of diastereoselective cycloadditions of enantiopure nitrilimines in aqueous media

Molteni, Giorgio

, p. 1077 - 1079 (2004)

The diastereoselective cycloadditions of enantiopure nitrilimines 4 with ethyl acrylate were exploited in dry toluene and in aqueous sodium hydrogencarbonate as reaction media. Shorter reaction times and improved diastereoisomeric ratios of the resulting 5-ethoxycarbonyl-4,5-dihydropyrazoles 5 and 6 were observed in aqueous media.
