130581-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130581-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,5,8 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130581-92:
(8*1)+(7*3)+(6*0)+(5*5)+(4*8)+(3*1)+(2*9)+(1*2)=109
109 % 10 = 9
So 130581-92-9 is a valid CAS Registry Number.

TOTAL SYNTHESIS OF GALANTIN I. REVISION OF THE ORIGINAL STRUCTURE
Sakai, Naomi,Ohfune, Yasufumi
, p. 3183 - 3186 (2007/10/02)
The proposed structure of galantin I, isolated as a mixture of homologs (1a/1b = 9/1), was shown to be incorrect by total synthesis and was revised twice to finally give 5a and 5c, respectively, by total synthesis.
