5544-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5544-20-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5544-20:
(6*5)+(5*5)+(4*4)+(3*4)+(2*2)+(1*0)=87
87 % 10 = 7
So 5544-20-7 is a valid CAS Registry Number.

Secondary amides activated with a Cbz group can be reduced to their corresponding hemiaminals using lithium borohydride. Hydrogenation then removes the Cbz and hydroxyl groups to produce the related amine. Tertiary amides are not affected.
