858745-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 858745-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,7,4 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 858745-19:
(8*8)+(7*5)+(6*8)+(5*7)+(4*4)+(3*5)+(2*1)+(1*9)=224
224 % 10 = 4
So 858745-19-4 is a valid CAS Registry Number.
