1256554-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1256554-18-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,5 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1256554-18:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*5)+(3*4)+(2*1)+(1*8)=163
163 % 10 = 3
So 1256554-18-3 is a valid CAS Registry Number.

A novel dibenzoazacyclooctyne precursor in regioselective copper-free click chemistry. An innovative 3-step synthesis

Starke, Frank,Walther, Martin,Pietzsch, Hans-Juergen

, p. 350 - 359 (2011/03/17)

A novel carboxylic acid substituted dibenzoazacyclooctyne precursor has been synthesized using a fast and innovative three-step synthesis. It can be easily converted into the corresponding alkyne through UV-irradiation. Due to its fast and regioselective
