81490-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81490-91-7 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, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81490-91:
(7*8)+(6*1)+(5*4)+(4*9)+(3*0)+(2*9)+(1*1)=137
137 % 10 = 7
So 81490-91-7 is a valid CAS Registry Number.
