146515-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146515-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,5,1 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 146515-56:
(8*1)+(7*4)+(6*6)+(5*5)+(4*1)+(3*5)+(2*5)+(1*6)=132
132 % 10 = 2
So 146515-56-2 is a valid CAS Registry Number.
