98206-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98206-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,0 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98206-39:
(7*9)+(6*8)+(5*2)+(4*0)+(3*6)+(2*3)+(1*9)=154
154 % 10 = 4
So 98206-39-4 is a valid CAS Registry Number.
