1451195-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1451195-27-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,1,1,9 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1451195-27:
(9*1)+(8*4)+(7*5)+(6*1)+(5*1)+(4*9)+(3*5)+(2*2)+(1*7)=149
149 % 10 = 9
So 1451195-27-9 is a valid CAS Registry Number.

Squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to nitroalkenes
Li, Jun-Hua,Du, Da-Ming
, p. 6215 - 6223 (2013/09/12)
An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to nitroalkenes has been developed. This reaction afforded the chiral pyrazol-3-ol derivatives in high to excellent yields (up to >99%) with high enantioselecti
