278187-50-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 278187-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,8,1,8 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 278187-50:
(8*2)+(7*7)+(6*8)+(5*1)+(4*8)+(3*7)+(2*5)+(1*0)=181
181 % 10 = 1
So 278187-50-1 is a valid CAS Registry Number.
