Check Digit Verification of cas no
The CAS Registry Mumber 63878-70-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,7 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 63878-70:
(7*6)+(6*3)+(5*8)+(4*7)+(3*8)+(2*7)+(1*0)=166
166 % 10 = 6
So 63878-70-6 is a valid CAS Registry Number.

A new method for the generation of the "PhSO2CF2Cu" species from readily available difluoromethyl phenyl sulfone (PhSO2CF2H) has been developed. The "PhSO2CF2Cu" reagent can be applied in (phenylsulfonyl)difluoromethylation of arylboronic acids, which affords a convenient approach to introducing the PhSO2CF2 group into aromatics.
