311820-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 311820-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,8,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 311820-40:
(8*3)+(7*1)+(6*1)+(5*8)+(4*2)+(3*0)+(2*4)+(1*0)=93
93 % 10 = 3
So 311820-40-3 is a valid CAS Registry Number.
