Check Digit Verification of cas no
The CAS Registry Mumber 139237-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,3 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139237-90:
(8*1)+(7*3)+(6*9)+(5*2)+(4*3)+(3*7)+(2*9)+(1*0)=144
144 % 10 = 4
So 139237-90-4 is a valid CAS Registry Number.
