Check Digit Verification of cas no

The CAS Registry Mumber 91638-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,3 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91638-69:
(7*9)+(6*1)+(5*6)+(4*3)+(3*8)+(2*6)+(1*9)=156
156 % 10 = 6
So 91638-69-6 is a valid CAS Registry Number.

Iterative stereospecific reagent-controlled homologation of pinacol boronates by enantioenriched α-chloroalkyllithium reagents

Blakemore, Paul R.,Burge, Matthew S.

, p. 3068 - 3069 (2008/02/05)

Reaction of pinacol boronates with putative enantioenriched α-chloroalkyllithium species, generated in situ from homochiral α-chloroalkylsulfoxides by sulfoxide ligand exchange with t-BuLi in PhMe at -78 °C, gave chain-extended boronic ester products with generally excellent stereochemical fidelity. Iteration of this stereospecific reagent-controlled homologation (StReCH) process enabled the programmed synthesis of all four stereoisomers of a stereodiad-containing model system (4-benzyl-1,6-diphenylhexan-2-ol) with er ≥ 97:3 in all cases.
