Check Digit Verification of cas no
The CAS Registry Mumber 18503-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,0 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18503-90:
(7*1)+(6*8)+(5*5)+(4*0)+(3*3)+(2*9)+(1*0)=107
107 % 10 = 7
So 18503-90-7 is a valid CAS Registry Number.
