Check Digit Verification of cas no
The CAS Registry Mumber 1138239-05-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,2,3 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1138239-05:
(9*1)+(8*1)+(7*3)+(6*8)+(5*2)+(4*3)+(3*9)+(2*0)+(1*5)=140
140 % 10 = 0
So 1138239-05-0 is a valid CAS Registry Number.
