Check Digit Verification of cas no
The CAS Registry Mumber 138035-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138035-68:
(8*1)+(7*3)+(6*8)+(5*0)+(4*3)+(3*5)+(2*6)+(1*8)=124
124 % 10 = 4
So 138035-68-4 is a valid CAS Registry Number.
