7784-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7784-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7784-90:
(6*7)+(5*7)+(4*8)+(3*4)+(2*9)+(1*0)=139
139 % 10 = 9
So 7784-90-9 is a valid CAS Registry Number.
