Check Digit Verification of cas no
The CAS Registry Mumber 293295-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,2,9 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 293295-99:
(8*2)+(7*9)+(6*3)+(5*2)+(4*9)+(3*5)+(2*9)+(1*9)=185
