Check Digit Verification of cas no
The CAS Registry Mumber 102520-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,5,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 102520-40:
(8*1)+(7*0)+(6*2)+(5*5)+(4*2)+(3*0)+(2*4)+(1*0)=61
61 % 10 = 1
So 102520-40-1 is a valid CAS Registry Number.
