512781-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 512781-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,2,7,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 512781-98:
(8*5)+(7*1)+(6*2)+(5*7)+(4*8)+(3*1)+(2*9)+(1*8)=155
155 % 10 = 5
So 512781-98-5 is a valid CAS Registry Number.

Highly functionalized pyrans designed for multipoint side chain attachment to the F-ring sector of spongistatin 1 (altohyrtin A)
Cho, Il Hwan,Paquette, Leo A.
, p. 43 - 46 (2007/10/03)
The synthesis of three potential F-ring components, variably functionalized for attachment to the chlorodiene side chain by differing chemical means, has been accomplished from D-(+)-mannose as the generic precursor.
