143391-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143391-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,9 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143391-20:
(8*1)+(7*4)+(6*3)+(5*3)+(4*9)+(3*1)+(2*2)+(1*0)=112
112 % 10 = 2
So 143391-20-2 is a valid CAS Registry Number.

Moustafa,Eisa
, p. 397 - 401 (2007/10/02)
3-(3 or 4-Acetylphenyl)-sydnones 7, 8 have been synthesized by formation of the glycines 3, 4, followed by nitrosation to 5, 6 and cyclization with acetic anhydride to sydnones. Sydnone derivatives carrying chalcone moieties 15, 16 were prepared by format
