113232-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113232-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,2,3 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 113232-70:
(8*1)+(7*1)+(6*3)+(5*2)+(4*3)+(3*2)+(2*7)+(1*0)=75
75 % 10 = 5
So 113232-70-5 is a valid CAS Registry Number.

Reaction of o-formyl-N,N-diethylbenzamides (5) with trimethylsilyl cyanide affords the corresponding (O-trimethylsilyl)cyanohydrins (6), which on treatment with acetic acid produce 3-cyanophthalides (7) in 80-90percent isolated yields.
