7739-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7739-90-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 7739-90:
(6*7)+(5*7)+(4*3)+(3*9)+(2*9)+(1*0)=134
134 % 10 = 4
So 7739-90-4 is a valid CAS Registry Number.
