870106-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 870106-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,1,0 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 870106-21:
(8*8)+(7*7)+(6*0)+(5*1)+(4*0)+(3*6)+(2*2)+(1*1)=141
141 % 10 = 1
So 870106-21-1 is a valid CAS Registry Number.
