157730-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157730-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,3 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157730-84:
(8*1)+(7*5)+(6*7)+(5*7)+(4*3)+(3*0)+(2*8)+(1*4)=152
152 % 10 = 2
So 157730-84-2 is a valid CAS Registry Number.

Catalytic enantioselective macrolide synthesis II: Use of differential deprotection protocols
Jones,Chapman,Huber,Beaty
, p. 1199 - 1202 (1994)
Catalytic enantioselective synthesis of Phorcantholide I has been achieved. Key stereochemistry was introduced using a chiral arene chromium tricarbonyl based catalyst to mediate the addition of dimethyl zinc to a functionalised aldehyde. During the synth
