176640-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176640-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,6,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 176640-18:
(8*1)+(7*7)+(6*6)+(5*6)+(4*4)+(3*0)+(2*1)+(1*8)=149
149 % 10 = 9
So 176640-18-9 is a valid CAS Registry Number.

Design and synthesis of bisubstrate analogues for 3-hydroxy-3-methyl-glutaryl coenzyme A reductase
Taillefumier,De Fornel,Chapleur
, p. 615 - 618 (1996)
The coupling of metalated pyridine derivatives with a chiral Weinreb amide derived from gluconolactone followed by stereoselective reduction of the resulting ketone are the key steps of the synthesis of bisubstrates analogues of the HMGCoA reduction by HMGR.
