Check Digit Verification of cas no
The CAS Registry Mumber 102266-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,6 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102266-69:
(8*1)+(7*0)+(6*2)+(5*2)+(4*6)+(3*6)+(2*6)+(1*9)=93
93 % 10 = 3
So 102266-69-3 is a valid CAS Registry Number.
