Check Digit Verification of cas no
The CAS Registry Mumber 201051-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,5 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201051-19:
(8*2)+(7*0)+(6*1)+(5*0)+(4*5)+(3*1)+(2*1)+(1*9)=56
56 % 10 = 6
So 201051-19-6 is a valid CAS Registry Number.
