EPA Substance Registry System: 5-Acetyl-2-mercapto-6-methyl-4-(3-nitro-phenyl)-1,4-dihydro-pyridine-3-carbonitrile; compound with piperidine(116736-41-5)
The CAS Registry Mumber 116736-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,7,3 and 6 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 116736-41: (8*1)+(7*1)+(6*6)+(5*7)+(4*3)+(3*6)+(2*4)+(1*1)=125 125 % 10 = 5 So 116736-41-5 is a valid CAS Registry Number.
