861855-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 861855-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,8,5 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 861855-21:
(8*8)+(7*6)+(6*1)+(5*8)+(4*5)+(3*5)+(2*2)+(1*1)=192
192 % 10 = 2
So 861855-21-2 is a valid CAS Registry Number.
