Check Digit Verification of cas no
The CAS Registry Mumber 5171-91-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5171-91:
(6*5)+(5*1)+(4*7)+(3*1)+(2*9)+(1*1)=85
85 % 10 = 5
So 5171-91-5 is a valid CAS Registry Number.

Cumyl phenyl sulfide forms bicumyl instead of cumyllithium upon reductive lithiation. Thiophenoxide as a leaving group in nucleophilic substitution by SET
Kulkarni, Vithalanand,Cohen, Theodore
, p. 12089 - 12100 (2007/10/03)
Upon reduction with aromatic radical-anions, cumyl phenyl sulfide (Is) yields mainly bicumyl (2) rather than the expected cumyllithium (3), despite a literature report, herein revealed to be in error, chat anion 3 is produced. Related examples from the literature are compiled. A suggested mechanism involves a single electron transfer from the generated cumyllithium (3) to the cumyl phenyl sulfide (Is) leading to thiophenoxide anion and two cumyl radicals, which mainly couple in a solvent cage. Such a thiophenoxide displacement by anion 3 has been demonstrated experimentally. Para tert-butyl groups, either on the phenyl or cumyl ring, increase the ratio of the cumylithium to the bicumyl, presumably by sterically inhibiting the pi complexation thought to be necessary for electron transfer.
