98206-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98206-33-8 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 98206-33:
(7*9)+(6*8)+(5*2)+(4*0)+(3*6)+(2*3)+(1*3)=148
148 % 10 = 8
So 98206-33-8 is a valid CAS Registry Number.
