The CAS Registry Mumber 35848-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,8,4 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35848-87:
(7*3)+(6*5)+(5*8)+(4*4)+(3*8)+(2*8)+(1*7)=154
154 % 10 = 4
So 35848-87-4 is a valid CAS Registry Number.

Cycloaddition reactions of 1,3-diazabuta-1,3-dienes with alkynyl ketenes

Abbiati, Giorgio,Contini, Alessandro,Nava, Donatella,Rossi, Elisabetta

experimental part, p. 4664 - 4670 (2009/10/09)

The cycloaddition reactions of 'all-carbon' 1,3-diazabuta-1,3-dienes with a few conjugated and unconjugated alkynyl ketenes are described. The reactions provide some interesting azetidinones and dihydropyrimidinones bearing an alkynyl moiety. The regiochemistry of cycloadduct is related with the degree of conjugation of the alkynyl ketene. Moreover, two alternative approaches to 'all-carbon' 1,3-diazabuta-1,3-dienes are reported.
