1053640-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1053640-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,3,6,4 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1053640-25:
(9*1)+(8*0)+(7*5)+(6*3)+(5*6)+(4*4)+(3*0)+(2*2)+(1*5)=117
117 % 10 = 7
So 1053640-25-7 is a valid CAS Registry Number.

Synthesis of the ezomycin octosyl nucleoside
Knapp,Shieh,Jeramillo,Trilles,Nandan
, p. 946 - 948 (2007/10/02)
Efficient chain extension of β-D-galactopyranosyl cyanide, cyclization to a bicyclic octose, and then attachment of cytosine affords the ezomycinoctosyl nucleoside 17 in a form suitable for elaboration to the ezomycins (e.g., 1).
