159892-32-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159892-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,9 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 159892-32:
(8*1)+(7*5)+(6*9)+(5*8)+(4*9)+(3*2)+(2*3)+(1*2)=187
187 % 10 = 7
So 159892-32-7 is a valid CAS Registry Number.
