63118-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63118-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 63118-40:
(7*6)+(6*3)+(5*1)+(4*1)+(3*8)+(2*4)+(1*0)=101
101 % 10 = 1
So 63118-40-1 is a valid CAS Registry Number.

o-Hydroxyphenylureas. Intermediates in the urea fusion synthesis of 2-benzoxazolinones
Nachman
, p. 1423 - 1425 (2007/10/02)
o-Hydroxyphenylureas have been identified as intermediates in the urea fusion synthesis of 2-benzoxazolinones. The pyrolysis of these intermediates represents a new alternate synthesis of the benzoxazolinone ring system.
