850997-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850997-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,9,9 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 850997-72:
(8*8)+(7*5)+(6*0)+(5*9)+(4*9)+(3*7)+(2*7)+(1*2)=217
217 % 10 = 7
So 850997-72-7 is a valid CAS Registry Number.
