1057342-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1057342-01-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,3,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1057342-01:
(9*1)+(8*0)+(7*5)+(6*7)+(5*3)+(4*4)+(3*2)+(2*0)+(1*1)=124
124 % 10 = 4
So 1057342-01-4 is a valid CAS Registry Number.

A new stereoselective synthesis of (±)-grandisol based on the remote alkylation protocol
Monteiro, Hugo J.,Stefani, Helio A.
, p. 2659 - 2663 (2007/10/03)
A new stereoselective synthesis of (±)-grandisol (1a) has been developed. The synthesis starts with a simple cyclobutyl derivative to which the methyl group and the 1,2-cis disposed side chains were appended through a remote alkylation protocol.
