1620217-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620217-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,2,1 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1620217-69:
(9*1)+(8*6)+(7*2)+(6*0)+(5*2)+(4*1)+(3*7)+(2*6)+(1*9)=127
127 % 10 = 7
So 1620217-69-7 is a valid CAS Registry Number.
