6903-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6903-12-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,0 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6903-12:
(6*6)+(5*9)+(4*0)+(3*3)+(2*1)+(1*2)=94
94 % 10 = 4
So 6903-12-4 is a valid CAS Registry Number.
