Check Digit Verification of cas no
The CAS Registry Mumber 119703-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,0 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119703-98:
(8*1)+(7*1)+(6*9)+(5*7)+(4*0)+(3*3)+(2*9)+(1*8)=139
139 % 10 = 9
So 119703-98-9 is a valid CAS Registry Number.

AN EPISULFONIUM ION MEDIATED RING EXPANSION OF 1-ALKENYLCYCLOALKANOLS
Kim, Sunggak,Park, Jung Ho
, p. 6181 - 6184 (2007/10/02)
It has been found that TBDMS ethers of 1-alkenylcycloalkanols are readily rearranged to the ring expanded α-(1-phenylthioalkyl)cycloalkanones in high yields via episulfonoium ions.
