904690-32-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904690-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,9 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 904690-32:
(8*9)+(7*0)+(6*4)+(5*6)+(4*9)+(3*0)+(2*3)+(1*2)=170
170 % 10 = 0
So 904690-32-0 is a valid CAS Registry Number.
