612040-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 612040-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,2,0,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 612040-76:
(8*6)+(7*1)+(6*2)+(5*0)+(4*4)+(3*0)+(2*7)+(1*6)=103
103 % 10 = 3
So 612040-76-3 is a valid CAS Registry Number.
