Check Digit Verification of cas no
The CAS Registry Mumber 137182-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,8 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137182-40:
(8*1)+(7*3)+(6*7)+(5*1)+(4*8)+(3*2)+(2*4)+(1*0)=122
122 % 10 = 2
So 137182-40-2 is a valid CAS Registry Number.
