71221-38-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71221-38-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,2 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71221-38:
(7*7)+(6*1)+(5*2)+(4*2)+(3*1)+(2*3)+(1*8)=90
90 % 10 = 0
So 71221-38-0 is a valid CAS Registry Number.

Phenylthio Migrations in Rearrangements of 2,2-Bisphenylthioethanols
Blatcher, Philip,Warren, Stuart
, p. 1055 - 1066 (2007/10/02)
Thionyl chloride causes rearrangement of the title compounds to give 2,3-bisphenylthiopropenes (12) by a phenylthio shift.The products undergo phenylthio shifts on exposure to light.Some applications to synthesis are described.
