1259331-44-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1259331-44-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,3,3 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1259331-44:
(9*1)+(8*2)+(7*5)+(6*9)+(5*3)+(4*3)+(3*1)+(2*4)+(1*4)=156
156 % 10 = 6
So 1259331-44-6 is a valid CAS Registry Number.

Acetalization of heptanal over Al-SBA-1 molecular sieve
Venkatachalam,Palanichamy,Murugesan
experimental part, p. 299 - 303 (2011/07/31)
Al-SBA-1 (Si/Al = 40, 80 and 120) and Al,Mg-SBA-1 (Si/(Al + Mg) = 40 and 80) molecular sieves were synthesized and characterized. Acetalization of n-heptanal with methanol was studied under autogenous pressure between 80 and 150 °C. Since protonation of n
