251293-70-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251293-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,2,9 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 251293-70:
(8*2)+(7*5)+(6*1)+(5*2)+(4*9)+(3*3)+(2*7)+(1*0)=126
126 % 10 = 6
So 251293-70-6 is a valid CAS Registry Number.

Synthesis of chiral [60]fullerene-steroid bisadducts using steroid templates
Ishi-i, Tsutomu,Shinkai, Seiji
, p. 12515 - 12530 (1999)
The double [4+2] cycloadditions between [60]fullerene and steroid- appended dibenzoates 7 and 8, the reaction sites of which were controlled by diols in chiral template molecules, afforded [60]fullerene-steroid bisadducts 11 and 12 regio- and chiroselecti
