61490-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61490-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61490-01:
(7*6)+(6*1)+(5*4)+(4*9)+(3*0)+(2*0)+(1*1)=105
105 % 10 = 5
So 61490-01-5 is a valid CAS Registry Number.
