90914-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90914-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,1 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90914-11:
(7*9)+(6*0)+(5*9)+(4*1)+(3*4)+(2*1)+(1*1)=127
127 % 10 = 7
So 90914-11-7 is a valid CAS Registry Number.
