Check Digit Verification of cas no

The CAS Registry Mumber 1268725-93-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,7,2 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1268725-93:
(9*1)+(8*2)+(7*6)+(6*8)+(5*7)+(4*2)+(3*5)+(2*9)+(1*3)=194
194 % 10 = 4
So 1268725-93-4 is a valid CAS Registry Number.

It's in the water! A new copper tertiary amine complex was prepared and applied in asymmetric Henry reactions in water and in the short synthesis of (S)-N-trans-feruloyl octopamine. This catalytic system provided an approach to the enantioselective Henry reaction of aldehydes with hydroxyl substituents (see graphic).
