893619-38-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 893619-38-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,6,1 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 893619-38:
(8*8)+(7*9)+(6*3)+(5*6)+(4*1)+(3*9)+(2*3)+(1*8)=220
220 % 10 = 0
So 893619-38-0 is a valid CAS Registry Number.
