Check Digit Verification of cas no
The CAS Registry Mumber 91025-04-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,2 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91025-04:
(7*9)+(6*1)+(5*0)+(4*2)+(3*5)+(2*0)+(1*4)=96
96 % 10 = 6
So 91025-04-6 is a valid CAS Registry Number.
