869997-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 869997-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,9,9 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 869997-83:
(8*8)+(7*6)+(6*9)+(5*9)+(4*9)+(3*7)+(2*8)+(1*3)=281
281 % 10 = 1
So 869997-83-1 is a valid CAS Registry Number.

Catalytic asymmetric reductive Michael cyclization
Yang, Jung Woon,Hechavarria Fonseca, Maria T.,List, Benjamin
, p. 15036 - 15037 (2007/10/03)
A highly efficient and chemo-, regio-, diastereo-, and enantioselective organocatalytic tandem conjugate reduction-Michael cyclization of enal enones has been developed. Accordingly, treating the enal enone with a Hantzsch dihydropyridine in the presence
