88159-85-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88159-85-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,5 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88159-85:
(7*8)+(6*8)+(5*1)+(4*5)+(3*9)+(2*8)+(1*5)=177
177 % 10 = 7
So 88159-85-7 is a valid CAS Registry Number.
