Check Digit Verification of cas no
The CAS Registry Mumber 17249-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,4 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17249-90:
(7*1)+(6*7)+(5*2)+(4*4)+(3*9)+(2*9)+(1*0)=120
120 % 10 = 0
So 17249-90-0 is a valid CAS Registry Number.
