Check Digit Verification of cas no
The CAS Registry Mumber 100850-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,5 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100850-03:
(8*1)+(7*0)+(6*0)+(5*8)+(4*5)+(3*0)+(2*0)+(1*3)=71
71 % 10 = 1
So 100850-03-1 is a valid CAS Registry Number.
