251958-14-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251958-14-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,5 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 251958-14:
(8*2)+(7*5)+(6*1)+(5*9)+(4*5)+(3*8)+(2*1)+(1*4)=152
152 % 10 = 2
So 251958-14-2 is a valid CAS Registry Number.

Total synthesis of clavepictines A and B. Diastereoselective cyclization of δ-aminoallenes
Du Ha, Jae,Cha, Jin Kun
, p. 10012 - 10020 (2007/10/03)
The stereocontrolled total synthesis of (-)-clavepictine A (1A) and (+)- clavepictine B (1B) has been accomplished in an enantioselective fashion, which has unequivocally established the absolute configuration of 1A and 1B. The pivotal step in the synthes
