Check Digit Verification of cas no

The CAS Registry Mumber 211187-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,1,8 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 211187-44:
(8*2)+(7*1)+(6*1)+(5*1)+(4*8)+(3*7)+(2*4)+(1*4)=99
99 % 10 = 9
So 211187-44-9 is a valid CAS Registry Number.

General strategies toward the syntheses of macrolide antibiotics. The total syntheses of 6-deoxyerythronolide B and oleandolide

Evans, David A.

, p. 5921 - 5942 (2007/10/03)

The asymmetric syntheses of 6-deoxyerythronolide B (1) and oleandolide (2) have been achieved, each in 18 linear steps. These syntheses demonstrate the utility of chiral β-keto imide building block 3 as a versatile building block for the aldol-based assemblage of polypropionate-derived natural products.
