Check Digit Verification of cas no

The CAS Registry Mumber 77796-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,9 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77796-40:
(7*7)+(6*7)+(5*7)+(4*9)+(3*6)+(2*4)+(1*0)=188
188 % 10 = 8
So 77796-40-8 is a valid CAS Registry Number.

Carbonyl and Thiocarbonyl Compounds: Part XV-Synthesis of Spiro and Quinazolinone Anils

Latif, N.,Mishriky, N.,Assad, Fahmy M.

, p. 118 - 120 (2007/10/02)

Tetrachloro-o-benzoquinone reacts with 2,3-diarylquinazoline-4(3H)-thiones (4a-c) to give spiro (5).The latter are cleaved with mineral acids to give 2,3-diarylquinazolin-4(3H)-ones (4d-f).Reaction of 5 with anilines affords the hitherto unknown quinazolinoneanils (6) together with tetrachlorocatechol.Reaction mechanisms are discussed.
