Check Digit Verification of cas no
The CAS Registry Mumber 127140-69-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,4 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127140-69:
(8*1)+(7*2)+(6*7)+(5*1)+(4*4)+(3*0)+(2*6)+(1*9)=106
106 % 10 = 6
So 127140-69-6 is a valid CAS Registry Number.
