Check Digit Verification of cas no
The CAS Registry Mumber 314042-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,4,0,4 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 314042-00:
(8*3)+(7*1)+(6*4)+(5*0)+(4*4)+(3*2)+(2*0)+(1*0)=77
77 % 10 = 7
So 314042-00-7 is a valid CAS Registry Number.
