159801-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159801-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,0 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 159801-73:
(8*1)+(7*5)+(6*9)+(5*8)+(4*0)+(3*1)+(2*7)+(1*3)=157
157 % 10 = 7
So 159801-73-7 is a valid CAS Registry Number.
