139215-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139215-31-9 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, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139215-31:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*5)+(2*3)+(1*1)=119
119 % 10 = 9
So 139215-31-9 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,
