Check Digit Verification of cas no
The CAS Registry Mumber 905859-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,8,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 905859-22:
(8*9)+(7*0)+(6*5)+(5*8)+(4*5)+(3*9)+(2*2)+(1*2)=195
195 % 10 = 5
So 905859-22-5 is a valid CAS Registry Number.
