98837-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98837-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,3 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98837-91:
(7*9)+(6*8)+(5*8)+(4*3)+(3*7)+(2*9)+(1*1)=203
203 % 10 = 3
So 98837-91-3 is a valid CAS Registry Number.

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.
