Check Digit Verification of cas no
The CAS Registry Mumber 69011-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,1 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 69011-22:
(7*6)+(6*9)+(5*0)+(4*1)+(3*1)+(2*2)+(1*2)=109
109 % 10 = 9
So 69011-22-9 is a valid CAS Registry Number.
