158665-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158665-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,6 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158665-25:
(8*1)+(7*5)+(6*8)+(5*6)+(4*6)+(3*5)+(2*2)+(1*5)=169
169 % 10 = 9
So 158665-25-9 is a valid CAS Registry Number.
