184435-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 184435-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,4,3 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 184435-81:
(8*1)+(7*8)+(6*4)+(5*4)+(4*3)+(3*5)+(2*8)+(1*1)=152
152 % 10 = 2
So 184435-81-2 is a valid CAS Registry Number.

, p. 2229 - 2248 (2007/10/03)
A convergent stereoselective total synthesis of (8′R)- and (8′S)-corossoline (1) has been performed via a multi-step process. Comparison of the mp, [α]D, ir and nmr data of both synthetic materials with those reported for natural corossoline did not allow
