187884-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187884-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,8,8 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 187884-96:
(8*1)+(7*8)+(6*7)+(5*8)+(4*8)+(3*4)+(2*9)+(1*6)=214
214 % 10 = 4
So 187884-96-4 is a valid CAS Registry Number.
