132816-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132816-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,1 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132816-20:
(8*1)+(7*3)+(6*2)+(5*8)+(4*1)+(3*6)+(2*2)+(1*0)=107
107 % 10 = 7
So 132816-20-7 is a valid CAS Registry Number.

, p. 467 - 470 (2007/10/02)
In the presence of catalytic to stoichiometric amounts of trimethylsilyl triflate, 1:1:1 mixtures of silyl ethers, phenyl(trimethylsilyl)sulfide, and aldehydes give O,S-acetals in fair to good yields.
