929897-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 929897-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,9,8,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 929897-21:
(8*9)+(7*2)+(6*9)+(5*8)+(4*9)+(3*7)+(2*2)+(1*1)=242
242 % 10 = 2
So 929897-21-2 is a valid CAS Registry Number.

Asymmetric total synthesis of martinelline and martinellic acid
Ikeda, Shuhei,Shibuya, Masatoshi,Iwabuchi, Yoshiharu
, p. 504 - 506 (2007/10/03)
Herein, we describe the first asymmetric total synthesis of (-)-martinelline ((-)-2) and the second total synthesis of (-)-martinellic acid ((-)-1) by employing a tandem Mukaiyama-Mannich reaction/aminal cyclization as the key step. The Royal Society of C
