157586-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157586-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,8 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157586-96:
(8*1)+(7*5)+(6*7)+(5*5)+(4*8)+(3*6)+(2*9)+(1*6)=184
184 % 10 = 4
So 157586-96-4 is a valid CAS Registry Number.
