146849-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146849-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,4 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146849-40:
(8*1)+(7*4)+(6*6)+(5*8)+(4*4)+(3*9)+(2*4)+(1*0)=163
163 % 10 = 3
So 146849-40-3 is a valid CAS Registry Number.
