Check Digit Verification of cas no
The CAS Registry Mumber 67990-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,9 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67990-76:
(7*6)+(6*7)+(5*9)+(4*9)+(3*0)+(2*7)+(1*6)=185
185 % 10 = 5
So 67990-76-5 is a valid CAS Registry Number.

PERFLUORO-ω-IODO-3-OXAALKANESULFONYL FLUORIDES AS INTERMEDIATES FOR SURFACTANTS AND VINYL COMPOUNDS

, p. 403 - 410 (2007/10/02)
Fluorosulfonyldifluoroacetyl fluoride (FOCCF2SO2F) quantitatively formed from sulfur trioxide and TFE through tetrafluoroethanesultone, has been converted into the octafluoro-5-iodo-3-oxapentanesulfonyl fluoride (ICF2CF2OCF2CF2SO2F) by the well known reaction involving MF, iodine and TFE in aprotic solvents.The iodo compound allowed us to obtain TFE telomers having both fluorosulfonyl and iodo terminal groups.These telomers were easily converted into the surfactants CF3CF2(CF2CF2)nOCF2F2SO3M by fluorination, and into the vinyl derivatives CF2=CF(CF2CF2)nOCF2CF2SO2F by dehalogenation.The scope of this study was to illustrate new methods for the synthesis of perfluoroalkane and perfluoroalkene sulfonates.
