1258277-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1258277-72-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1258277-72:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*7)+(3*7)+(2*7)+(1*2)=183
183 % 10 = 3
So 1258277-72-3 is a valid CAS Registry Number.

experimental part, p. 3405 - 3414 (2011/01/12)

Various imidates 3 were successfully synthesized from naphthopyrans and ethyl orthoesters in moderate yields. These intermediates undergo rapid condensation with several primary amines to give the corresponding 11-aryl-1,12-dihydro-11H-naphthopyrano[2,3-d
