159897-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159897-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,9 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159897-50:
(8*1)+(7*5)+(6*9)+(5*8)+(4*9)+(3*7)+(2*5)+(1*0)=204
204 % 10 = 4
So 159897-50-4 is a valid CAS Registry Number.
