Check Digit Verification of cas no

The CAS Registry Mumber 1240525-85-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,2 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240525-85:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*2)+(3*5)+(2*8)+(1*5)=122
122 % 10 = 2
So 1240525-85-2 is a valid CAS Registry Number.

Synthesis and spectral studies of photochromism of 1,3-benzoxazinone spiropyrans

Popov,Shcherbakov,Bulanov,Kobeleva,Valova,Barachevsky

, p. 2418 - 2422 (2009)

Photochromism of the spiropyran derivatives of the 1,3-benzoxazinone series was studied. A relationship between the structure of substituents and photochromic properties of the compounds was revealed.

Investigation of complexation of functionalized 1,3-benzoxazinone spiropyrans with metal ions

Barachevskii,Kobeleva,Valova,Popov,Shcherbakov,Bulanov,Kogan

experimental part, p. 2787 - 2791 (2010/05/14)

For the first time, complexation between the metal ions and the molecules of photochromic benzooxazine spiropyrans was found and studied. The observed spectral-kinetic changes are explained by the complex formation between molecules of the merocyanine typ
