841200-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 841200-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,1,2,0 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 841200-01:
(8*8)+(7*4)+(6*1)+(5*2)+(4*0)+(3*0)+(2*0)+(1*1)=109
109 % 10 = 9
So 841200-01-9 is a valid CAS Registry Number.
