Check Digit Verification of cas no
The CAS Registry Mumber 1391521-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,5,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1391521-99:
(9*1)+(8*3)+(7*9)+(6*1)+(5*5)+(4*2)+(3*1)+(2*9)+(1*9)=165
165 % 10 = 5
So 1391521-99-5 is a valid CAS Registry Number.
