Check Digit Verification of cas no

The CAS Registry Mumber 258281-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,2,8 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 258281-81:
(8*2)+(7*5)+(6*8)+(5*2)+(4*8)+(3*1)+(2*8)+(1*1)=161
161 % 10 = 1
So 258281-81-1 is a valid CAS Registry Number.

Oxidative Cleavage of Silyl Ethers by an Oxoammonium Salt

Loman, Jacob J.,Pistritto, Vincent A.,Kelly, Christopher B.,Leadbeater, Nicholas E.

, p. 2372 - 2377 (2016)

A method for the oxidative cleavage of silyl ethers to their corresponding carbonyl species mediated by an oxoammonium salt is described. The resulting aldehydes and ketones are obtained under mild reaction conditions with no observed overoxidation. For robust substrates, heating to reflux temperatures significantly reduces the reaction time.
