Check Digit Verification of cas no

The CAS Registry Mumber 913832-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,8,3 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 913832-80:
(8*9)+(7*1)+(6*3)+(5*8)+(4*3)+(3*2)+(2*8)+(1*0)=171
171 % 10 = 1
So 913832-80-1 is a valid CAS Registry Number.

Total synthesis of (-)-himgaline

Shah, Unmesh,Chackalamannil, Samuel,Ganguly, Ashit K.,Chelliah, Mariappan,Kolotuchin, Sergei,Buevich, Alexei,McPhail, Andrew

, p. 12654 - 12655 (2008/02/05)

The first total synthesis of (-)-himgaline and a highly enantioselective synthesis of its congener (-)-GB 13 are described. Decarboxylative aza-Michael reaction of the hexacyclic lactone precursor under acidic conditions, followed by basic workup, yielded (-)-GB 13 in 80% yield. Cyclization of (-)-GB 13 to oxohimgaline under acidic conditions, followed by internally coordinated sodium triacetoxyborohydride reduction, gave (-)-himgaline as the exclusive product. Copyright
