1207173-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1207173-33-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,1,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1207173-33:
(9*1)+(8*2)+(7*0)+(6*7)+(5*1)+(4*7)+(3*3)+(2*3)+(1*3)=118
118 % 10 = 8
So 1207173-33-8 is a valid CAS Registry Number.

On the structure of penipratynolene and WA
Jian, Ya-Jun,Wu, Yikang
, p. 637 - 640 (2010)
The antipode of the structure proposed for the natural product penipratynolene in the literature was synthesized in high enantiopurity via an chiron approach and fully characterized. However, substantial differences were observed between the physical and
