98043-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98043-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,4 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98043-65:
(7*9)+(6*8)+(5*0)+(4*4)+(3*3)+(2*6)+(1*5)=153
153 % 10 = 3
So 98043-65-3 is a valid CAS Registry Number.
