1333317-69-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1333317-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,3,1 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1333317-69:
(9*1)+(8*3)+(7*3)+(6*3)+(5*3)+(4*1)+(3*7)+(2*6)+(1*9)=133
133 % 10 = 3
So 1333317-69-3 is a valid CAS Registry Number.

Page/Page column 29, (2013/06/27)

The present invention relates to compounds, particularly but not exclusively, compounds for use as catalysts, methods for producing said compounds and the use of said compounds as catalysts in catalytic processes including, but not limited to, the asymmetric reduction of imine and enamine compounds and/or the reductive amination of ketone compounds. The compounds have the formula 1 wherein: R1, R2, R3, R4 and R5 are each separately selected from the group consisting of hydrogen, alkyl and aryl; X is oxygen or sulfur; W is selected from the group consisting of – OR18,–SR18, –NR19R20, –PR19R20 where R18 is alkyl or aryl, and R19 and R20 are each separately selected from the group consisting of hydrogen, alkyl and aryl; and Z has the formula 2 wherein: R6 and R7 are each separately selected from the group consisting of hydrogen, alkoxy, nitro, halogen, alkyl and aryl, or R6 and R7 are linked to form a cyclic group; and Y is oxygen, sulfur or NR10 in which R10 is selected from the group consisting of hydrogen, alkyl and aryl.
