Check Digit Verification of cas no
The CAS Registry Mumber 102553-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,5,5 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 102553-01:
(8*1)+(7*0)+(6*2)+(5*5)+(4*5)+(3*3)+(2*0)+(1*1)=75
75 % 10 = 5
So 102553-01-5 is a valid CAS Registry Number.
