163801-99-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163801-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,0 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 163801-99:
(8*1)+(7*6)+(6*3)+(5*8)+(4*0)+(3*1)+(2*9)+(1*9)=138
138 % 10 = 8
So 163801-99-8 is a valid CAS Registry Number.
