Check Digit Verification of cas no

The CAS Registry Mumber 180072-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,0,7 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180072-75:
(8*1)+(7*8)+(6*0)+(5*0)+(4*7)+(3*2)+(2*7)+(1*5)=117
117 % 10 = 7
So 180072-75-7 is a valid CAS Registry Number.

A contribution to the asymmetric synthesis of 3-amine β-lactams: The diastereoselective [2+2] cycloaddition reaction of chiral aminoketene equivalents with enolizable aldehyde-derived/mines

Palomo, Claudio,Aizpurua, Jesus M.,Legido, Marta,Mielgo, Antonia,Galarza, Regina

, p. 1432 - 1441 (2007/10/03)

N-[Bis(trimethylsilyl)methyl]imines 9 show unique chemical properties when compared with conventional imines. Their reaction with optically pure aminoketenes derived from dehydrochlorination of 14 and 15 affords the corresponding 3-amino-4-alkyl-β-lactams
