Check Digit Verification of cas no
The CAS Registry Mumber 125683-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,8 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125683-05:
(8*1)+(7*2)+(6*5)+(5*6)+(4*8)+(3*3)+(2*0)+(1*5)=128
128 % 10 = 8
So 125683-05-8 is a valid CAS Registry Number.
