688738-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 688738-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,7,3 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 688738-99:
(8*6)+(7*8)+(6*8)+(5*7)+(4*3)+(3*8)+(2*9)+(1*9)=250
250 % 10 = 0
So 688738-99-0 is a valid CAS Registry Number.
