Check Digit Verification of cas no
The CAS Registry Mumber 100221-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,2,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100221-85:
(8*1)+(7*0)+(6*0)+(5*2)+(4*2)+(3*1)+(2*8)+(1*5)=50
50 % 10 = 0
So 100221-85-0 is a valid CAS Registry Number.

New synthesis of polyfluoroalkanesulfonylureas
Benfodda,Delon,Guillen,Blancou
, p. 1353 - 1358 (2008/09/18)
This study describes a new synthesis of F-alkanesulfonyl ureas by reaction of the sodium salt of perfluoroalkane sulfonamide (RF = C4F9, C6F13) with some isocyanates in anhydrous THF. The perfluorinated sulfonylureas are obtained, in one step, from moderate to good yields.
