Check Digit Verification of cas no

The CAS Registry Mumber 178422-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,4,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 178422-63:
(8*1)+(7*7)+(6*8)+(5*4)+(4*2)+(3*2)+(2*6)+(1*3)=154
154 % 10 = 4
So 178422-63-4 is a valid CAS Registry Number.

-

Page/Page column 5, (2008/06/13)

The present invention relates to a process for preparing mono-N-sulphonylated diamines by reacting diamines with sulphonyl halides in the presence of water, base and organic solvents.

Process for preparing mono-N-sulfonylated diamines

-

Page/Page column 8, (2008/06/13)

Production of mono-N-sulfonylated diamine compounds comprises reaction of a diamine compound with a sulfonyl halide in the presence of water, organic solvent and a base. Production of mono-N-sulfonylated diamine compounds (I) of formula (1) comprises reaction of a diamine compound of formula (2) with a sulfonyl halide of formula (3) in the presence of water, organic solvent and a base. R3SO2X (3) R1 and R2 = 1-20C alkyl, 4-15C aryl, 5-16C arylalkyl or R1 and R2 together form a 3-12C alkylene; R3 = 1-20C alkyl, optionally fluorinated or 4-15C aryl; and X = F, Cl, Br or I. Independent claims are also included for the following: (1) solutions (II) containing the mono-N-sulfonylated diamine compounds (I) prepared by the process followed by at least partial removal of water; and (2) catalysts (III) prepared from the solutions (II) by reaction with organometallic compounds of formula (4). (MXn(R4))2 (4) M = Ru, Rh or Ir; R4 = 6-12C aryl, optionally substituted by 1-8C alkyl, benzyl or phenyl, or cyclopentadienyl optionally substituted by up to 5 groups or indenyl; and n = 1 or 2.
