192573-98-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 192573-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,5,7 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 192573-98:
(8*1)+(7*9)+(6*2)+(5*5)+(4*7)+(3*3)+(2*9)+(1*8)=171
171 % 10 = 1
So 192573-98-1 is a valid CAS Registry Number.

Studies towards the synthesis of the zaragozic acids: Synthesis of the bicyclic acetal core of zaragozic acid C.
Paterson, Ian,Fessner, Klaus,Finlay, M. Raymond V.
, p. 4301 - 4304 (2007/10/03)
The bicyclic core 6 of zaragozic acid C (7) was prepared by the epoxide cyclisation reaction 21 → 22 → 15. Acetal 15 was also obtained by acid-promoted rearrangement of the isomeric acetal 19.
