1309870-85-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309870-85-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,7 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1309870-85:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*7)+(3*0)+(2*8)+(1*5)=176
176 % 10 = 6
So 1309870-85-6 is a valid CAS Registry Number.
