Check Digit Verification of cas no
The CAS Registry Mumber 100942-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100942-31:
(8*1)+(7*0)+(6*0)+(5*9)+(4*4)+(3*2)+(2*3)+(1*1)=82
82 % 10 = 2
So 100942-31-2 is a valid CAS Registry Number.
