698976-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 698976-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,8,9,7 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 698976-27:
(8*6)+(7*9)+(6*8)+(5*9)+(4*7)+(3*6)+(2*2)+(1*7)=261
261 % 10 = 1
So 698976-27-1 is a valid CAS Registry Number.

Studies on the synthesis of croomine: Synthesis of the tricyclic B,C,D-ring core structure
Lindsay, Karl B.,Pyne, Stephen G.
, p. 779 - 782 (2007/10/03)
A convergent and asymmetric synthesis of the tricyclic B,C,D-ring core structure of croomine has been achieved, using aminolysis reactions of chiral vinyl epoxides and the RCM reaction.
