79909-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79909-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,0 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 79909-65:
(7*7)+(6*9)+(5*9)+(4*0)+(3*9)+(2*6)+(1*5)=192
192 % 10 = 2
So 79909-65-2 is a valid CAS Registry Number.

5-Alkylidenefuran-2(5H)-ones can be synthesized efficiently from S-methyl 5-oxo-2,5-dihydro-furanylidenealkanethioates by treatment with Raney nickel.The ylidenealkanethioates are prepared from the Wittig reactions between cyclic anhydrides and (methylthi
