Check Digit Verification of cas no

The CAS Registry Mumber 142055-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,5 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142055-34:
(8*1)+(7*4)+(6*2)+(5*0)+(4*5)+(3*5)+(2*3)+(1*4)=93
93 % 10 = 3
So 142055-34-3 is a valid CAS Registry Number.

Highly diastereoselective alkylation of 6-methylperihydropyrimidin-4-ones directed towards the synthesis of α-substituted β-amino acids

Amoroso,Cardillo,Tomasini

, p. 2725 - 2728 (2007/10/02)

The highly diastereoselective alkylation of 6-methylperihydropyrimidin-4-ones 1 and 2 has been reported. The corresponding lithium enolates have been alkylated under a variety of conditions with good trans selectivity and all the reaction products have been easily separated and characterised.
