1323952-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1323952-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,3,9,5 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1323952-69:
(9*1)+(8*3)+(7*2)+(6*3)+(5*9)+(4*5)+(3*2)+(2*6)+(1*9)=157
157 % 10 = 7
So 1323952-69-7 is a valid CAS Registry Number.

A flexible approach to 6,5-benzannulated spiroketals
Wilson, Zoe E.,Hubert, Jonathan G.,Brimble, Margaret A.
experimental part, p. 3938 - 3945 (2011/09/14)
A novel route to simple 6,5-benzannulated spiroketal analogues has been developed. A convergent Horner-Wadsworth-Emmons olefination enabled ready assembly of the spiroketal precursors. Use of a benzyl protecting group strategy enabled an efficient one-pot
