187220-82-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187220-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,2 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 187220-82:
(8*1)+(7*8)+(6*7)+(5*2)+(4*2)+(3*0)+(2*8)+(1*2)=142
142 % 10 = 2
So 187220-82-2 is a valid CAS Registry Number.
