24785-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24785-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,8 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.Calculate Digit Verification of CAS Registry Number 24785-40:
(7*2)+(6*4)+(5*7)+(4*8)+(3*5)+(2*4)+(1*0)=128
128 % 10 = 8
So 24785-40-8 is a valid CAS Registry Number.
