1297531-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1297531-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,5,3 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1297531-41:
(9*1)+(8*2)+(7*9)+(6*7)+(5*5)+(4*3)+(3*1)+(2*4)+(1*1)=179
179 % 10 = 9
So 1297531-41-9 is a valid CAS Registry Number.

Stereoselective synthesis of a model C(18)-C(35) spiroketal fragment of integramycin
Sun, Huikai,Abbott, Jason R.,Roush, William R.
, p. 2734 - 2737 (2011/07/30)
A highly stereoselective synthesis of a model C(18)-C(35) spiroketal unit (7) of integramycin has been accomplished via an enantioselective stannyl-crotylboration reaction and an N-iodosuccinimide-mediated spiroketalization of 19a.
