Lookchem provides you with multiple data and supplier information of this chemical.
The CAS Registry Mumber 99285-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,8 and 5 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 99285-17: (7*9)+(6*9)+(5*2)+(4*8)+(3*5)+(2*1)+(1*7)=183 183 % 10 = 3 So 99285-17-3 is a valid CAS Registry Number.
