Check Digit Verification of cas no
The CAS Registry Mumber 1426657-66-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,6,5 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1426657-66:
(9*1)+(8*4)+(7*2)+(6*6)+(5*6)+(4*5)+(3*7)+(2*6)+(1*6)=180
180 % 10 = 0
So 1426657-66-0 is a valid CAS Registry Number.
