154701-53-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154701-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,7,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154701-53:
(8*1)+(7*5)+(6*4)+(5*7)+(4*0)+(3*1)+(2*5)+(1*3)=118
118 % 10 = 8
So 154701-53-8 is a valid CAS Registry Number.

Chiral, non-racemic, bicyclic lactam 1 (X=Y=H) bearing an angular hydrogen at C-7a (1, R=H), underwent efficient diastereoselective dialkylation producing the quaternary substituted lactams 1 (X=Y=alkyl).The latter were transformed into carbinol amines 5
