Check Digit Verification of cas no

The CAS Registry Mumber 177415-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,4,1 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 177415-48:
(8*1)+(7*7)+(6*7)+(5*4)+(4*1)+(3*5)+(2*4)+(1*8)=154
154 % 10 = 4
So 177415-48-4 is a valid CAS Registry Number.

A highly efficient synthesis of (2R,3S,5S)-2-acetoxy-3-fluoro-5-(p-toluoyloxymethyl)tetrahydrofuran (2a) was developed. As a key intermediate, 2a was effectively applied to the synthesis of 9-(2,3-dideoxy-2-fluoro-β-D-threo-pentofuranosyl)adenine (FddA), thus, providing a practical synthetic approach to FddA.
