1374425-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374425-57-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,4,2 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1374425-57:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*2)+(3*5)+(2*5)+(1*7)=166
166 % 10 = 6
So 1374425-57-6 is a valid CAS Registry Number.

A chiral-pool-based approach to the core structure of (+)-hyperforin
Richard, Jean-Alexandre,Chen, David Y.-K.
, p. 484 - 487 (2012/03/08)
Asymmetric entry to the bicyclic core structure of (+)-hyperforin is presented. The developed synthetic strategy features a carefully orchestrated stereochemical relay from the single chiral center residing within (-)-Wieland-Miescher ketone and an intram
