222835-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222835-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,8,3 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 222835-57:
(8*2)+(7*2)+(6*2)+(5*8)+(4*3)+(3*5)+(2*5)+(1*7)=126
126 % 10 = 6
So 222835-57-6 is a valid CAS Registry Number.
