Check Digit Verification of cas no
The CAS Registry Mumber 120807-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,0 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120807-16:
(8*1)+(7*2)+(6*0)+(5*8)+(4*0)+(3*7)+(2*1)+(1*6)=91
91 % 10 = 1
So 120807-16-1 is a valid CAS Registry Number.
