870274-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 870274-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,2,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 870274-40:
(8*8)+(7*7)+(6*0)+(5*2)+(4*7)+(3*4)+(2*4)+(1*0)=171
171 % 10 = 1
So 870274-40-1 is a valid CAS Registry Number.
