Check Digit Verification of cas no
The CAS Registry Mumber 338386-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,3,8 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 338386-43:
(8*3)+(7*3)+(6*8)+(5*3)+(4*8)+(3*6)+(2*4)+(1*3)=169

, p. 1053 - 1056 (2007/10/03)
[structure: see text]. A formal synthesis of the muscarinic M(1) receptor antagonist (-)-TAN1251A (7) from L-tyrosine is described. Central to this venture has been the construction of the 1-azaspiro[4.5]decane skeleton present in the natural product by a
