885133-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 885133-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,1,3 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 885133-69:
(8*8)+(7*8)+(6*5)+(5*1)+(4*3)+(3*3)+(2*6)+(1*9)=197
197 % 10 = 7
So 885133-69-7 is a valid CAS Registry Number.
