219715-80-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219715-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,1 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219715-80:
(8*2)+(7*1)+(6*9)+(5*7)+(4*1)+(3*5)+(2*8)+(1*0)=147
147 % 10 = 7
So 219715-80-7 is a valid CAS Registry Number.
