Check Digit Verification of cas no
The CAS Registry Mumber 135671-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135671-20:
(8*1)+(7*3)+(6*5)+(5*6)+(4*7)+(3*1)+(2*2)+(1*0)=124
124 % 10 = 4
So 135671-20-4 is a valid CAS Registry Number.

Treatment of XCF2CO2Me (X = Cl, Br) with organic halides in the presence of KF and catalytic amounts of CuI at 80-120 deg C for 3-8 h in DMF gave long-chain perfluoroalkylated compounds which are considered to be former by the insertions of CF2(..) into carbon-copper bonds.
