98156-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98156-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,5 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98156-84:
(7*9)+(6*8)+(5*1)+(4*5)+(3*6)+(2*8)+(1*4)=174
174 % 10 = 4
So 98156-84-4 is a valid CAS Registry Number.
