Check Digit Verification of cas no
The CAS Registry Mumber 180861-07-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,8,6 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 180861-07:
(8*1)+(7*8)+(6*0)+(5*8)+(4*6)+(3*1)+(2*0)+(1*7)=138
138 % 10 = 8
So 180861-07-8 is a valid CAS Registry Number.
