Check Digit Verification of cas no
The CAS Registry Mumber 127869-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,6 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127869-19:
(8*1)+(7*2)+(6*7)+(5*8)+(4*6)+(3*9)+(2*1)+(1*9)=166
166 % 10 = 6
So 127869-19-6 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.
