Check Digit Verification of cas no
The CAS Registry Mumber 91025-69-3 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, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91025-69:
(7*9)+(6*1)+(5*0)+(4*2)+(3*5)+(2*6)+(1*9)=113
