536976-92-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 536976-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,6,9,7 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 536976-92:
(8*5)+(7*3)+(6*6)+(5*9)+(4*7)+(3*6)+(2*9)+(1*2)=208
208 % 10 = 8
So 536976-92-8 is a valid CAS Registry Number.

, p. 1643 - 1646 (2007/10/03)
An efficient and stereodefined strategy is described for the first asymmetric synthesis of a new type of pyrrolizidine alkaloids, amphorogynine A and its 1-epi-isomer. The key 2,4-disubstituted pyrrolidine ring was constructed by elaboration of the chiral
