870283-65-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 870283-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,2,8 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 870283-65:
(8*8)+(7*7)+(6*0)+(5*2)+(4*8)+(3*3)+(2*6)+(1*5)=181
181 % 10 = 1
So 870283-65-1 is a valid CAS Registry Number.
