1207997-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1207997-71-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,9,9 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1207997-71:
(9*1)+(8*2)+(7*0)+(6*7)+(5*9)+(4*9)+(3*7)+(2*7)+(1*1)=184
184 % 10 = 4
So 1207997-71-4 is a valid CAS Registry Number.

Nucleotides: Part LXXV. New types of fluorescence labeling of 2′-deoxycytidine
Maier, Thomas,Pfleiderer, Wolfgang
experimental part, p. 2722 - 2736 (2010/04/04)
The reactivity of the 2′-deoxy-N4-(phenoxycarbonyl) cytidine derivatives 3 and 4 with aromatic amines was studied to form new types of urea derivatives (see 5 - 10). On the same basis, labeling of 3 and 4 with 5-aminofluorescein (14) was achiev
