193475-29-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193475-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,4,7 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 193475-29:
(8*1)+(7*9)+(6*3)+(5*4)+(4*7)+(3*5)+(2*2)+(1*9)=165
165 % 10 = 5
So 193475-29-5 is a valid CAS Registry Number.

Synthesis of Okadaic Acid-Tautomycin Hybrid
Tsuboi, Katsunori,Ichikawa, Yoshiyasu,Isobe, Minoru
, p. 713 - 715 (2007/10/03)
One of the three spiro-segments in the synthesis of okadaic acid was synthesized under a new heteroconjugate addition strategy. Successive coupling of this spiro-segment with two tautomycin-synthetic segments afforded a hybrid molecule between okadaic acid and tautomycin.
