148372-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148372-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,3,7 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 148372-19:
(8*1)+(7*4)+(6*8)+(5*3)+(4*7)+(3*2)+(2*1)+(1*9)=144
144 % 10 = 4
So 148372-19-4 is a valid CAS Registry Number.

Oppolzer, Wolfgang,Merifield, Eric
, p. 957 - 962 (1993)
Enantiomerically pure (-)-pinidine (1) has been synthesized in 18.5 percent overall yield by a nine-step sequence starting from keto-ester 2.The key step 5 -> 6 involves an asymmetric, electrophilic enolate hydroxyamination.Diastereoselective hydrogenatio
