187400-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187400-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,4,0 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 187400-08:
(8*1)+(7*8)+(6*7)+(5*4)+(4*0)+(3*0)+(2*0)+(1*8)=134
134 % 10 = 4
So 187400-08-4 is a valid CAS Registry Number.
