Check Digit Verification of cas no

The CAS Registry Mumber 27888-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,8 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 27888-23:
(7*2)+(6*7)+(5*8)+(4*8)+(3*8)+(2*2)+(1*3)=159
159 % 10 = 9
So 27888-23-9 is a valid CAS Registry Number.

α-Isocyanatoacrylonitriles from alkylidene- or arylidenecyanoacetic acids; synthesis and reactions

Jaafar,Francis,Danion-Bougot,Danion

, p. 56 - 60 (2007/10/02)

The Curtius reaction converts alkylidene- or arylidenecyanoacetic acids to α-isocyanatoacrylonitriles in a stereospecific way. These versatile intermediates allow an easy access to arylacetic acids and various amino acid derivatives, as well as β-lactams or 2-azabutadienes.
