135484-89-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135484-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,8 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135484-89:
(8*1)+(7*3)+(6*5)+(5*4)+(4*8)+(3*4)+(2*8)+(1*9)=148
148 % 10 = 8
So 135484-89-8 is a valid CAS Registry Number.
