The "CIS" designation indicates that the two substituents are on the same side of the ring. The "1S,2R" notation indicates the stereochemistry of the compound, specifying that the carbon at position 1 has an S (sinister) configuration and the carbon at position 2 has an R (rectus) configuration. The "CBZ" group on the nitrogen atom refers to a carboxybenzyl protecting group. CIS-(1S,2R)-1N-CBZ-CYCLOHEXANE-1,2-DIAMINE is commonly used in organic synthesis and medicinal chemistry as a building block for the preparation of various pharmaceuticals and biologically active molecules.
Check Digit Verification of cas no
The CAS Registry Mumber 1067631-21-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,7,6,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1067631-21:
(9*1)+(8*0)+(7*6)+(6*7)+(5*6)+(4*3)+(3*1)+(2*2)+(1*1)=143
143 % 10 = 3
So 1067631-21-3 is a valid CAS Registry Number.
