310405-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 310405-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,0,4,0 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 310405-08:
(8*3)+(7*1)+(6*0)+(5*4)+(4*0)+(3*5)+(2*0)+(1*8)=74
74 % 10 = 4
So 310405-08-4 is a valid CAS Registry Number.
