Check Digit Verification of cas no
The CAS Registry Mumber 25095-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,9 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25095-94:
(7*2)+(6*5)+(5*0)+(4*9)+(3*5)+(2*9)+(1*4)=117
117 % 10 = 7
So 25095-94-7 is a valid CAS Registry Number.
