1219617-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1219617-72-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,6,1 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1219617-72:
(9*1)+(8*2)+(7*1)+(6*9)+(5*6)+(4*1)+(3*7)+(2*7)+(1*2)=157
157 % 10 = 7
So 1219617-72-7 is a valid CAS Registry Number.
