491874-35-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 491874-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,7 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 491874-35:
(8*4)+(7*9)+(6*1)+(5*8)+(4*7)+(3*4)+(2*3)+(1*5)=192
192 % 10 = 2
So 491874-35-2 is a valid CAS Registry Number.

, p. 781 - 787 (2007/10/03)
We have used the reaction of 4-aminodiphenyl ester with acrylic, methacrylic, crotonic, and itaconic acids to synthesize N-substituted β-alanines, which undergo ring closure to form derivatives of dihydropyrimidinedione and 4-carboxy-2-pyrrolidinone. We h
