501683-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 501683-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,6,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 501683-31:
(8*5)+(7*0)+(6*1)+(5*6)+(4*8)+(3*3)+(2*3)+(1*1)=124
124 % 10 = 4
So 501683-31-4 is a valid CAS Registry Number.
