Check Digit Verification of cas no

The CAS Registry Mumber 1257244-29-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,4 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257244-29:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*4)+(3*4)+(2*2)+(1*9)=153
153 % 10 = 3
So 1257244-29-3 is a valid CAS Registry Number.

Highly stereoselective synthesis of indanes with four stereogenic centers via sequential Michael reaction and [3+2] cycloaddition

Chua, Pei Juan,Tan, Bin,Yang, Limin,Zeng, Xiaofei,Zhu, Di,Zhong, Guofu

, p. 7611 - 7613 (2010)

A highly efficient organocatalytic sequential reaction involving Michael addition of bis(phenylsulfonyl)ethylene, in situ condensation and intramolecular nitrone [3+2] cycloaddition with a variety of aldehydes and hydroxyamines to afford a single diastereomer of indanes with four stereogenic centers in excellent yields and stereoselectivities was developed.
