1251422-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1251422-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,1,4,2 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1251422-87:
(9*1)+(8*2)+(7*5)+(6*1)+(5*4)+(4*2)+(3*2)+(2*8)+(1*7)=123
123 % 10 = 3
So 1251422-87-3 is a valid CAS Registry Number.

A short and efficient construction of the dibenzo[c,h]chromen-6-one skeleton
Delioemeroglu, Murat K.,Oezcan, Sevil,Balcia, Metin
experimental part, p. 148 - 160 (2010/08/04)
We hereby report a major revision of the synthetic methodology for construction of the dibenzochromenone skeleton. Homophthalic acid derivatives were reacted with thionylchloride/DMF in the presence of NaN 3. As the main product, dibenzochromen
