Check Digit Verification of cas no
The CAS Registry Mumber 102740-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,4 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102740-19:
(8*1)+(7*0)+(6*2)+(5*7)+(4*4)+(3*0)+(2*1)+(1*9)=82
82 % 10 = 2
So 102740-19-2 is a valid CAS Registry Number.
