81490-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81490-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,9 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81490-75:
(7*8)+(6*1)+(5*4)+(4*9)+(3*0)+(2*7)+(1*5)=137
137 % 10 = 7
So 81490-75-7 is a valid CAS Registry Number.
