Check Digit Verification of cas no
The CAS Registry Mumber 139888-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,8,8 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139888-76:
(8*1)+(7*3)+(6*9)+(5*8)+(4*8)+(3*8)+(2*7)+(1*6)=199
199 % 10 = 9
So 139888-76-9 is a valid CAS Registry Number.
