197845-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197845-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,8,4 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 197845-74:
(8*1)+(7*9)+(6*7)+(5*8)+(4*4)+(3*5)+(2*7)+(1*4)=202
202 % 10 = 2
So 197845-74-2 is a valid CAS Registry Number.

Use of a lithiolactone in the enantioselective constructions of A/C seco-B and of A/B seco-C proTaxol systems
Stork, Gilbert,Doi, Takayuki,Liu, Longbin
, p. 7471 - 7474 (2007/10/03)
We show that an unusual lithiolactone system is a useful starting point for the construction of various intermediates to the taxol structure.
