287970-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 287970-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,9,7 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 287970-52:
(8*2)+(7*8)+(6*7)+(5*9)+(4*7)+(3*0)+(2*5)+(1*2)=199
199 % 10 = 9
So 287970-52-9 is a valid CAS Registry Number.
