Check Digit Verification of cas no

The CAS Registry Mumber 197857-42-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,8,5 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 197857-42:
(8*1)+(7*9)+(6*7)+(5*8)+(4*5)+(3*7)+(2*4)+(1*2)=204
204 % 10 = 4
So 197857-42-4 is a valid CAS Registry Number.

On the Reaction between Alkyl Isocyanides and 3-Benzylidene-2,4-pentanedione. A Convenient Synthetic Route to Densely Functionalized Furans

Yavari,Shaabani,Maghsoodlou

, p. 697 - 700 (1997)

Alkyl isocyanides undergo a formal (1 + 4] cycloaddition reaction with 3-benzylidene-2,4-pentanedione yielding multiply functionalized furan ring systems in fairly high yields. The 1H NMR spectrum of 4-acetyl -2-(N-benzylamino)-5-methyl-3-pnenylfuran shows an AB pattern for the benzylic methylene protons as a result of a restricted rotation about the bond between the acetyl group and the furan ring, thus giving rise to perpendicular disymmetric planes.
