143504-32-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143504-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,0 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143504-32:
(8*1)+(7*4)+(6*3)+(5*5)+(4*0)+(3*4)+(2*3)+(1*2)=99
99 % 10 = 9
So 143504-32-9 is a valid CAS Registry Number.

S(N)2-type reaction of 3-O-(s1-imidazyl)sulfonyl-1,2:5,6-di-O-isopropylidene-α-D-glucofuran ose with benzoate gave the 3-O-benzoyl-α-D-allo derivative 2, which was hydrolysed to give the 5,6-diol 3. Compound 3 was converted into the 6-deoxy-6-iodo derivat
