139215-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139215-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139215-19:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*5)+(2*1)+(1*9)=123
123 % 10 = 3
So 139215-19-3 is a valid CAS Registry Number.

"Bicyclobenzodiazepinones" from 3-oxo-1,2-diazetidinium hydroxide, inner salts
Taylor, Edward C.,Sobieray, Denis M.
, p. 9599 - 9620 (2007/10/02)
1,3-Dipolar cycloaddition of benzyne with 3-oxo-1,2-diazetidinium hydroxide, inner salts leads to tricyclic adducts which have been termed "bicyclobenzodiazepinones" because of their structural relationship to 1,4-benzodiazepinones. In analogous fashion,
