Check Digit Verification of cas no
The CAS Registry Mumber 676-88-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 676-88:
(5*6)+(4*7)+(3*6)+(2*8)+(1*8)=100
100 % 10 = 0
So 676-88-0 is a valid CAS Registry Number.

In anhydrous methylene chloride, nitrosonium tetrafluoroborate and dimethyl sulphide reacted to give a fairly stable red-brown solution at -70 deg C which slowly decomposed at ca. -20 deg C to afford trimethylsulphonium tetrafluoroborate.The red-brown solution reacted with olefins to afford 2-nitrosoalkyldimethylsulphonium salts and/or 1,2-bis-sulphonium salts, and with anisole to give p-methoxyphenyldimethylsulphonium salt.The reactions were interpreted as involving the electrophilic dimethyl sulphide cation radical as a reactive intermediate leading the attack on the ?-bond systems.This is followed by radical combination or electron transfer-elimination to complete the addition and substitution pathways.
