678187-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 678187-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,8 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 678187-85:
(8*6)+(7*7)+(6*8)+(5*1)+(4*8)+(3*7)+(2*8)+(1*5)=224
224 % 10 = 4
So 678187-85-4 is a valid CAS Registry Number.
