912457-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 912457-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,2,4,5 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 912457-34:
(8*9)+(7*1)+(6*2)+(5*4)+(4*5)+(3*7)+(2*3)+(1*4)=162
162 % 10 = 2
So 912457-34-2 is a valid CAS Registry Number.

De novo asymmetric synthesis of milbemycin β3 via an iterative asymmetric hydration approach
Li, Miaosheng,O'Doherty, George A.
, p. 3987 - 3990 (2007/10/03)
The enantioselective synthesis of the spiroketal/macrolide natural product milbemycin β3 has been achieved in 22 steps and 2.8% overall yield from an achiral dienoate. The spiroketal ring system was installed by three sequential asymmetric hydr
