Check Digit Verification of cas no

The CAS Registry Mumber 869541-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,5,4 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 869541-51:
(8*8)+(7*6)+(6*9)+(5*5)+(4*4)+(3*1)+(2*5)+(1*1)=215
215 % 10 = 5
So 869541-51-5 is a valid CAS Registry Number.

Practical and Broadly Applicable Catalytic Enantioselective Additions of Allyl-B(pin) Compounds to Ketones and α-Ketoesters

Robbins, Daniel W.,Lee, KyungA,Silverio, Daniel L.,Volkov, Alexey,Torker, Sebastian,Hoveyda, Amir H.

supporting information, p. 9610 - 9614 (2016/08/10)

A set of broadly applicable methods for efficient catalytic additions of easy-to-handle allyl-B(pin) (pin=pinacolato) compounds to ketones and acyclic α-ketoesters was developed. Accordingly, a large array of tertiary alcohols can be obtained in 60 to >98 % yield and up to 99:1 enantiomeric ratio. At the heart of this development is rational alteration of the structures of the small-molecule aminophenol-based catalysts. Notably, with ketones, increasing the size of a catalyst moiety (tBu to SiPh3) results in much higher enantioselectivity. With α-ketoesters, on the other hand, not only does the opposite hold true, since Me substitution leads to substantially higher enantioselectivity, but the sense of the selectivity is reversed as well.
