Check Digit Verification of cas no
The CAS Registry Mumber 1219799-61-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,7,9 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1219799-61:
(9*1)+(8*2)+(7*1)+(6*9)+(5*7)+(4*9)+(3*9)+(2*6)+(1*1)=197
197 % 10 = 7
So 1219799-61-7 is a valid CAS Registry Number.

A new route to 1,4-oxazepanes and 1,4-diazepanes from Garner aldehyde
Das, Sanjit Kumar,Srivastava, Ajay Kumar,Panda, Gautam
, p. 1483 - 1485 (2010)
A highly efficient and convenient method for the synthesis of substituted chiral 1,4-oxazepanes and 1,4-diazepanes have been described from Garner aldehyde through reductive amination with amino ester hydrochlorides followed by intramolecular cyclization as the key steps.
