Check Digit Verification of cas no

The CAS Registry Mumber 1251901-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,1,9,0 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1251901-67:
(9*1)+(8*2)+(7*5)+(6*1)+(5*9)+(4*0)+(3*1)+(2*6)+(1*7)=133
133 % 10 = 3
So 1251901-67-3 is a valid CAS Registry Number.

Influence of β-substituents in aldol reactions of boron enolates of β-alkoxy methylketones

Dias, Luiz C.,De Lucca Jr., Emilio C.,Ferreira, Marco A. B.,Garcia, Danilo C.,Tormena, Claudio F.

, p. 5056 - 5059 (2010)

Moderate to good levels of substrate-based 1,5-syn-stereocontrol could be achieved in the boron-mediated aldol reactions of β-tert-butyl methylketones with achiral aldehydes, independent of the nature of the β-alkoxy protecting group (P = PMB or TBS). The
