Check Digit Verification of cas no

The CAS Registry Mumber 1192256-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,2,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1192256-28:
(9*1)+(8*1)+(7*9)+(6*2)+(5*2)+(4*5)+(3*6)+(2*2)+(1*8)=152
152 % 10 = 2
So 1192256-28-2 is a valid CAS Registry Number.

Synthesis of macrocyclic scaffolds suitable for diversity-oriented synthesis of macrolides

Grimwood, Michael E.,Hansen, Henrik C.

supporting information; experimental part, p. 8132 - 8138 (2010/01/16)

Synthesis of macrocyclic glycal-based scaffolds for diversity-oriented synthesis was studied and demonstrated using macrocyclic enyne ring-closing metathesis. The roles of ring size, alkyne substitution, and orientation relative to the glycal were studied. In all cases, the cyclization showed preference for the thermodynamically favored endo-mode of closure and a trans-double bond at the ring-closure site, leaving macrocyclic scaffolds all containing multiple orthogonal functional groups available for further diversification.
