355409-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 355409-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,5,4,0 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 355409-87:
(8*3)+(7*5)+(6*5)+(5*4)+(4*0)+(3*9)+(2*8)+(1*7)=159
159 % 10 = 9
So 355409-87-9 is a valid CAS Registry Number.
