Lookchem provides you with multiple data and supplier information of this chemical.
The CAS Registry Mumber 56423-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,2 and 3 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 56423-20: (7*5)+(6*6)+(5*4)+(4*2)+(3*3)+(2*2)+(1*0)=112 112 % 10 = 2 So 56423-20-2 is a valid CAS Registry Number.
