Check Digit Verification of cas no

The CAS Registry Mumber 226226-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,2,2 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 226226-31:
(8*2)+(7*2)+(6*6)+(5*2)+(4*2)+(3*6)+(2*3)+(1*1)=109
109 % 10 = 9
So 226226-31-9 is a valid CAS Registry Number.

Total synthesis of 3-deoxy-D-manno-2-octulosonic acid (KDO) and 2-deoxy-β-KDO

Burke, Steven D.,Sametz, Geoffrey M.

, p. 71 - 74 (2008/02/11)

(equation presented) Total syntheses of KDO and 2-deoxy-β-KDO are reported. The C2-symmetric dienediol 4 was desymmetrized by conversion to its corresponding 1,4-dioxanone 5. Ireland-Claisen rearrangement of 5 provided the 6-vinyldihydropyran-2-carboxylate template 6. Double-Sharpless asymmetric dihydroxylation gave the tetraol 7a, which was converted to KDO and 2-deoxy-β-KDO using methods similar to those previously reported. This synthetic scheme provides a flexible route to KDO and KDO analogues.
