1325653-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1325653-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,5,6,5 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1325653-53:
(9*1)+(8*3)+(7*2)+(6*5)+(5*6)+(4*5)+(3*3)+(2*5)+(1*3)=149
149 % 10 = 9
So 1325653-53-9 is a valid CAS Registry Number.

, p. 4652 - 4655 (2011/11/06)
A convergent synthesis of (+)-SCH 351448 (1), a monosodium salt of a C 2-symmetric macrodiolide, is described. Our approach is based on a [4 + 2] annulation with a chiral allyl silane (anti-5c) to assemble the pyran subunits. Homodimerization w
