84332-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84332-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,3 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84332-98:
(7*8)+(6*4)+(5*3)+(4*3)+(3*2)+(2*9)+(1*8)=139
139 % 10 = 9
So 84332-98-9 is a valid CAS Registry Number.
