897931-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 897931-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,7,9,3 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 897931-63:
(8*8)+(7*9)+(6*7)+(5*9)+(4*3)+(3*1)+(2*6)+(1*3)=244
244 % 10 = 4
So 897931-63-4 is a valid CAS Registry Number.
