100844-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100844-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100844-74:
(8*1)+(7*0)+(6*0)+(5*8)+(4*4)+(3*4)+(2*7)+(1*4)=94
94 % 10 = 4
So 100844-74-4 is a valid CAS Registry Number.
