Check Digit Verification of cas no

The CAS Registry Mumber 111009-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,0 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111009-19:
(8*1)+(7*1)+(6*1)+(5*0)+(4*0)+(3*9)+(2*1)+(1*9)=59
59 % 10 = 9
So 111009-19-9 is a valid CAS Registry Number.

REGIOSPECIFIC PREPARATION AND ALLYLATION OF FLUOROMETHYL KETONE ENOL ETHERS VIA FLUORO-OLEFINATION OF 1,2,3-TRIOL DERIVATIVES

Shimizu, Makoto,Nakahara, Yuko,Kanemoto,Shigekazu,Yoshioka, Hirosuke

, p. 1677 - 1680 (1987)

Fluoromethyl ketone enol ethers are regiospecifically prepared in good yields by treatment of 2-alkoxy-1,3-bis(t-butyldimethylsiloxy)alkene with TBAF-MsF, and subsequent thermal (3,3)-sigmatropic rearrangement on the 2-alkenyl enol ethers gives α-allylate
