Check Digit Verification of cas no

The CAS Registry Mumber 206658-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,6,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 206658-53:
(8*2)+(7*0)+(6*6)+(5*6)+(4*5)+(3*8)+(2*5)+(1*3)=139
139 % 10 = 9
So 206658-53-9 is a valid CAS Registry Number.

Synthesis of N1-unsubstituted β-lactams via a facile deprotection of N1-[(α-thiophenyl)benzyl] group

Karupaiyan,Srirajan,Deshmukh,Bhawal

, p. 4375 - 4386 (1998)

A diastereoselective synthesis of (±) c/s-β-1actams (5 and 6) via cycloaddition reactions of N1-(α-thiophenyl)benzyl imines (3) with acid chlorides (4) in the presence of triethylamine is described. The deprotection of N1-(α-thiophenyl)benzyl group has been achieved by oxidation using potassium persulfate to give N-unsubstituted β-lactams (7) in good yields.
