147085-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147085-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,0,8 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 147085-54:
(8*1)+(7*4)+(6*7)+(5*0)+(4*8)+(3*5)+(2*5)+(1*4)=139
139 % 10 = 9
So 147085-54-9 is a valid CAS Registry Number.
