76980-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76980-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,8 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76980-71:
(7*7)+(6*6)+(5*9)+(4*8)+(3*0)+(2*7)+(1*1)=177
177 % 10 = 7
So 76980-71-7 is a valid CAS Registry Number.

TRANSFORMATIONS OF POLYCYCLIC KETONES. XVI. AMMONOLYSIS OF 3-PHENYL-9-HYDROXYPHENALENONE
Solodar', S. L.,Vinogradov, L. M.
, p. 1805 - 1808 (2007/10/02)
The ammonolysis of 3-phenyl-9-hydroxyphenalenone gives a mixture of isomeric 3-phenyl-9-amino- and 7-phenyl-9-aminophenalenones, from which 3-phenyl-9-bromo- and 7-phenyl-9-bromophenalenones were synthesized.
