111221-74-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111221-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,2 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 111221-74:
(8*1)+(7*1)+(6*1)+(5*2)+(4*2)+(3*1)+(2*7)+(1*4)=60
60 % 10 = 0
So 111221-74-0 is a valid CAS Registry Number.

Cobalt-Catalyzed Intramolecular Silylperoxidation of Unsaturated Diisopropylsilyl Ethers
Oswald, Jonathan P.,Woerpel
, p. 7564 - 7574 (2019/06/17)
A cobalt-catalyzed intramolecular silylperoxidation reaction was developed that allows for the conversion of unsaturated diisopropylsilyl ethers to 3-sila-1,2,4-trioxepanes. Reduction of the peroxide unit of the 3-sila-1,2,4-trioxepane yields six-membered
