Check Digit Verification of cas no
The CAS Registry Mumber 106683-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,6,8 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106683-19:
(8*1)+(7*0)+(6*6)+(5*6)+(4*8)+(3*3)+(2*1)+(1*9)=126
126 % 10 = 6
So 106683-19-6 is a valid CAS Registry Number.
