145668-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145668-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,6 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145668-40:
(8*1)+(7*4)+(6*5)+(5*6)+(4*6)+(3*8)+(2*4)+(1*0)=152
152 % 10 = 2
So 145668-40-2 is a valid CAS Registry Number.
