Calculate Digit Verification of CAS Registry Number 143245-68:
(8*1)+(7*4)+(6*3)+(5*2)+(4*4)+(3*5)+(2*6)+(1*8)=115
115 % 10 = 5
So 143245-68-5 is a valid CAS Registry Number.

Effects of chain length on behavior of biradicals generated from Norrish type I reaction of 2,2-diphenylcycloalkanones. Isolation and photochemistry of intermediate methylenecyclohexadienyl ketones

Tanaka,Suzuki,Yamaguchi,Misawa,Sakuragi,Tokumaru

, p. 3651 - 3654 (1992)

The reaction course of biradicals, O=C(↑)-(CH2)(n-2)-C(↑)Ph2, generated from Norrish type I reaction of 2,2-diphenylcycloalkanones with various ring sizes, is switched from intramolecular disproportionation (n = 6,7) to acyl-phenyl r
