2902-39-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2902-39-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2902-39:
(6*2)+(5*9)+(4*0)+(3*2)+(2*3)+(1*9)=78
78 % 10 = 8
So 2902-39-8 is a valid CAS Registry Number.
