188539-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188539-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,3 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188539-95:
(8*1)+(7*8)+(6*8)+(5*5)+(4*3)+(3*9)+(2*9)+(1*5)=199
199 % 10 = 9
