1621132-90-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1621132-90-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,1,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1621132-90:
(9*1)+(8*6)+(7*2)+(6*1)+(5*1)+(4*3)+(3*2)+(2*9)+(1*0)=118
118 % 10 = 8
So 1621132-90-8 is a valid CAS Registry Number.

Photoactivatable fluorescein derivatives caged with a (3-hydroxy-2- naphthalenyl)methyl group
Nekongo, Emmanuel E.,Popik, Vladimir V.
, p. 7665 - 7671 (2014/09/17)
The (3-hydroxy-2-naphthalenyl)methyl (NQMP) group represents an efficient photocage for fluorescein-based dyes. Thus, irradiation of the 6-NQMP ether of 2'-hydroxymethylfluorescein with low-intensity UVA light results in a 4-fold increase in emission inte
