90798-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90798-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90798-77:
(7*9)+(6*0)+(5*7)+(4*9)+(3*8)+(2*7)+(1*7)=179
179 % 10 = 9
So 90798-77-9 is a valid CAS Registry Number.
