90925-63-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90925-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,2 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90925-63:
(7*9)+(6*0)+(5*9)+(4*2)+(3*5)+(2*6)+(1*3)=146
146 % 10 = 6
So 90925-63-6 is a valid CAS Registry Number.
