23269-46-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23269-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,6 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23269-46:
(7*2)+(6*3)+(5*2)+(4*6)+(3*9)+(2*4)+(1*6)=107
107 % 10 = 7
So 23269-46-7 is a valid CAS Registry Number.

o-(α-Benzotriazolylalkyl)phenols: Novel precursors of o-quinone methides
Katritzky,Lan
, p. 761 - 764 (2007/10/02)
1-[α-(Benzotriazol-1-yl)alkyl]-2-napthols and 2-[(benzotriazol-1-yl)methyl]phenols have been shown to lose a molecule of benzotriazole to generate o-quinone methides, which can be trapped with electron-rich olefins (ethyl vinyl ether, 1-vinyl-2-pyrrolidin
