Check Digit Verification of cas no

The CAS Registry Mumber 124603-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,0 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124603-53:
(8*1)+(7*2)+(6*4)+(5*6)+(4*0)+(3*3)+(2*5)+(1*3)=98
98 % 10 = 8
So 124603-53-8 is a valid CAS Registry Number.

New Trialkylsilyl Enol Ether Chemistry: α-N-Tosylamination of Triisopropylsilyl Enol Ethers

Magnus, Philip,Lacour, Jerome,Coldham, Iain,Mugrage, Benjamin,Bauta, William B.

, p. 11087 - 11110 (2007/10/02)

Triisopropylsilyl enol ethers react with (TsN)2Se to give α-N-tosylamino derivatives in modest to good yields.In the absence of 1,3-diaxial interactions the N-tosylamino group prefers an axial conformation.The axial N-tosylamino derivatives can be readily transformed into the azabicyclononane skeleton, the core structure of a number of alkaloids.
