Check Digit Verification of cas no
The CAS Registry Mumber 13925-06-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,2 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13925-06:
(7*1)+(6*3)+(5*9)+(4*2)+(3*5)+(2*0)+(1*6)=99
99 % 10 = 9
So 13925-06-9 is a valid CAS Registry Number.
