146335-31-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146335-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 146335-31:
(8*1)+(7*4)+(6*6)+(5*3)+(4*3)+(3*5)+(2*3)+(1*1)=121
121 % 10 = 1
So 146335-31-1 is a valid CAS Registry Number.
