245064-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 245064-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,0,6 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 245064-78:
(8*2)+(7*4)+(6*5)+(5*0)+(4*6)+(3*4)+(2*7)+(1*8)=132
132 % 10 = 2
So 245064-78-2 is a valid CAS Registry Number.
