146901-66-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146901-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,0 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 146901-66:
(8*1)+(7*4)+(6*6)+(5*9)+(4*0)+(3*1)+(2*6)+(1*6)=138
138 % 10 = 8
So 146901-66-8 is a valid CAS Registry Number.
