Check Digit Verification of cas no
The CAS Registry Mumber 133615-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,1 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133615-08:
(8*1)+(7*3)+(6*3)+(5*6)+(4*1)+(3*5)+(2*0)+(1*8)=104
104 % 10 = 4
So 133615-08-4 is a valid CAS Registry Number.

Furylvinylhalides. XI. Reactions of β-(5-Nitrofur-2-yl)-β-chloro-α-cyanoacrylic Acid Derivatives with Enamines
Vieth, Siegfried,Jaehnisch, Klaus
, p. 687 - 693 (2007/10/02)
Enamines are vinylated by β-(5-nitrofur-2-yl)-β-chloro-α-cyanoacrylic acid derivatives 2 yielding push-pull-dienes 3, 4 or 6.Acidic ring closure of 3 leads to pyridin-2-ones 7 or chromen-2-ones 8, respectively.
