1258861-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258861-66-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,8,6 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1258861-66:
(9*1)+(8*2)+(7*5)+(6*8)+(5*8)+(4*6)+(3*1)+(2*6)+(1*6)=193
193 % 10 = 3
So 1258861-66-3 is a valid CAS Registry Number.

Studies on synthesis of the C-1 to C-18 fragment of pamamycins 607 and 621A
Ren, Guobao,Wu, Yikang
experimental part, p. 1651 - 1659 (2011/08/02)
Some efforts directed towards synthesis of the C-1 to C-18 fragment of natural antibiotic pamamycins 607 and 621A are disclosed. The nine stereogenic centers in the fragment were installed using a chiral auxiliary-induced asymmetric aldol reaction, a chir
