Check Digit Verification of cas no
The CAS Registry Mumber 1243142-35-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,1,4 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1243142-35:
(9*1)+(8*2)+(7*4)+(6*3)+(5*1)+(4*4)+(3*2)+(2*3)+(1*5)=109
109 % 10 = 9
So 1243142-35-9 is a valid CAS Registry Number.
