Check Digit Verification of cas no

The CAS Registry Mumber 1627503-04-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,7,5,0 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1627503-04:
(9*1)+(8*6)+(7*2)+(6*7)+(5*5)+(4*0)+(3*3)+(2*0)+(1*4)=151
151 % 10 = 1
So 1627503-04-1 is a valid CAS Registry Number.

Metal-free oxidative cyclization of o-acylphenols for the construction of 2-aminobenzofuran-3(2H)-ones

Yu, Hui,Huang, Weihua,Zhang, Fengling

, p. 3156 - 3162 (2014)

An efficient metal-free approach to the synthesis of 2-aminobenzofuran- 3(2H)-ones has been developed. Using TBHP as an oxidant and I2 (or TBAI) as catalyst, 2-acylphenols were treated with secondary amines to provide 2-aminobenzofuran-3(2H)-one derivatives in moderate to good yields. A possible reaction pathway for the formation of 2-dimorpholinobenzofuran-3(2H)-one is also discussed herein. Copyright
