897919-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 897919-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,7,9,1 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 897919-50:
(8*8)+(7*9)+(6*7)+(5*9)+(4*1)+(3*9)+(2*5)+(1*0)=255
255 % 10 = 5
So 897919-50-5 is a valid CAS Registry Number.
