Check Digit Verification of cas no
The CAS Registry Mumber 109137-86-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,3 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109137-86:
(8*1)+(7*0)+(6*9)+(5*1)+(4*3)+(3*7)+(2*8)+(1*6)=122
122 % 10 = 2
So 109137-86-2 is a valid CAS Registry Number.
