90402-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90402-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,0 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90402-38:
(7*9)+(6*0)+(5*4)+(4*0)+(3*2)+(2*3)+(1*8)=103
103 % 10 = 3
So 90402-38-3 is a valid CAS Registry Number.
