188633-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188633-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,3 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188633-68:
(8*1)+(7*8)+(6*8)+(5*6)+(4*3)+(3*3)+(2*6)+(1*8)=183
183 % 10 = 3
So 188633-68-3 is a valid CAS Registry Number.
