851676-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 851676-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,6,7 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 851676-69:
(8*8)+(7*5)+(6*1)+(5*6)+(4*7)+(3*6)+(2*6)+(1*9)=202
202 % 10 = 2
So 851676-69-2 is a valid CAS Registry Number.
