308796-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 308796-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,7,9 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 308796-30:
(8*3)+(7*0)+(6*8)+(5*7)+(4*9)+(3*6)+(2*3)+(1*0)=167
167 % 10 = 7
So 308796-30-7 is a valid CAS Registry Number.

The synthesis of 1,2-diarylindenes via DDQ-mediated dehydrogenative intramolecular cyclization
Li, Yi,Cao, Li,Luo, Xiaoyan,Deng, Wei-Ping
, p. 5974 - 5979 (2015/03/30)
A direct DDQ-mediated dehydrogenative intramolecular cyclization of (Z)-1,2,3-triaryl substituted propylenes promoted by Cu(OAc)2 was developed, providing 1,2-diarylindene derivatives in moderate to good yields (up to 92%) under mild conditions
