Check Digit Verification of cas no

The CAS Registry Mumber 245356-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,3,5 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 245356-64:
(8*2)+(7*4)+(6*5)+(5*3)+(4*5)+(3*6)+(2*6)+(1*4)=143
143 % 10 = 3
So 245356-64-3 is a valid CAS Registry Number.

Alkenyl diols by E-Selective Horner-Wittig elimination: Formal synthesis of any isomer (RR, RS, SR or SS) bearing 1,5-related stereogenic centres across an E double bond

Nelson, Adam,Warren, Stuart

, p. 1633 - 1636 (1998)

Oxidation of diastereomerically pure diphenylphosphinoyl furans [e.g. 4-benzyloxy-2-diphenylphosphinoyl 1-(2'-furyl) octan-1-ol] with m-CPBA, followed by reduction with sodium borohydride, gives triols with four stereochemically controlled stereogenic centres. (E)-Selective Horner-Wittig elimination removes the middle two stereogenic centres to yield diols with 1,5-related stereogenic centres across a trans double bond.
