815654-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 815654-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,5,6,5 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 815654-41:
(8*8)+(7*1)+(6*5)+(5*6)+(4*5)+(3*4)+(2*4)+(1*1)=172
172 % 10 = 2
So 815654-41-2 is a valid CAS Registry Number.

Several N(-hydroxyalkyl)-2,4-dinitroanilines were transformed into their phosphoramidites (see 5 and 6 in Scheme 1) in view of their use as fluorescence quenchers, and modified 2-aminobenzamides (see 9, 10, 18, and 19 in Scheme 1) were applied in model re
