188446-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188446-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,4,4 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188446-67:
(8*1)+(7*8)+(6*8)+(5*4)+(4*4)+(3*6)+(2*6)+(1*7)=185
185 % 10 = 5
So 188446-67-5 is a valid CAS Registry Number.
