Check Digit Verification of cas no
The CAS Registry Mumber 1951439-46-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,9,5,1,4,3 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1951439-46:
(9*1)+(8*9)+(7*5)+(6*1)+(5*4)+(4*3)+(3*9)+(2*4)+(1*6)=195
195 % 10 = 5
So 1951439-46-5 is a valid CAS Registry Number.
