Check Digit Verification of cas no
The CAS Registry Mumber 120219-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,1 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120219-69:
(8*1)+(7*2)+(6*0)+(5*2)+(4*1)+(3*9)+(2*6)+(1*9)=84
84 % 10 = 4
So 120219-69-4 is a valid CAS Registry Number.
