Check Digit Verification of cas no

The CAS Registry Mumber 4903-40-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4903-40:
(6*4)+(5*9)+(4*0)+(3*3)+(2*4)+(1*0)=86
86 % 10 = 6
So 4903-40-6 is a valid CAS Registry Number.

THE CHEMISTRY OF LACTIM ETHERS. V. REACTION OF LACTIM THIOETHERS WITH β-AMINOESTERS

Takahata, Hiroki,Tomoguchi, Akira,Yamazaki, Takao

, p. 2525 - 2530 (2007/10/02)

Reaction of a cyclic β-aminoester such as 2-ethoxycarbonylmethylpiperidine (5) with the lactim thioethers 1b and 1c gave a 10-membered cyclic diamide (7) and an 11-membered ring compound (9), respectively.On the other hand, though acyclic β-aminoesters (6) reacted with 1 to afford methyl 3-methylthiopropionate (11), N-alkyl 3-methylthiopropionamide (12), lactams (13), and amidines (14), no cyclic diamide was obtained.Keywords: - lactim thioethers; cyclic β-aminoesters; acyclic β-aminoesters; cyclic diamide; medium-ring; methyl 3-methylthiopropionate; N-alkyl 3-methylthiopionamide; amidines; lactams; β-lactmams
