312745-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312745-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,7,4 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 312745-80:
(8*3)+(7*1)+(6*2)+(5*7)+(4*4)+(3*5)+(2*8)+(1*0)=125
125 % 10 = 5
So 312745-80-5 is a valid CAS Registry Number.
