Check Digit Verification of cas no

The CAS Registry Mumber 1985-15-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1985-15:
(6*1)+(5*9)+(4*8)+(3*5)+(2*1)+(1*5)=105
105 % 10 = 5
So 1985-15-5 is a valid CAS Registry Number.

The Reactivity of Silyl Ethers to the Swern Reagent

Afonso, Carlos M.,Barros, M. Teresa,Maycock, Christopher D.

, p. 1221 - 1224 (2007/10/02)

The activated Me2SO reagent , 'Swern reagent'> oxidises the trimethylsilyl ethers of primary and secondary alcohols directly to the corresponding carbonyl compound.Useful selectivity is possible where competing ether groups possess large differences of steric hindrance.Dimethyl-t-butylsilyl ethers are unaffected by this reagent.
