1271212-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1271212-21-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,1,2,1 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1271212-21:
(9*1)+(8*2)+(7*7)+(6*1)+(5*2)+(4*1)+(3*2)+(2*2)+(1*1)=105
105 % 10 = 5
So 1271212-21-5 is a valid CAS Registry Number.

Synthesis and characterization of some new carbazolyloxy substituted oxazinane derivatives
Reddy,Mukkanti,Chakravarthy,Reddy
experimental part, p. 3299 - 3306 (2010/11/02)
Some new carbazolyloxy substituted oxazinane derivatives such as morpholinonyl, morpholinedionyl and morpholinyl were synthesized by cyclizing the corresponding carbazolyloxy propanolamine moiety using different two carbon sources.
