853956-02-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853956-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,9,5 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 853956-02:
(8*8)+(7*5)+(6*3)+(5*9)+(4*5)+(3*6)+(2*0)+(1*2)=202
202 % 10 = 2
So 853956-02-2 is a valid CAS Registry Number.
